I bought a macbook pro on november 2011 wich had Lion OS installed on it. Playback plug-in in Mainstage 2.1.3 does not play files from the beginning (it leaves out like 50 mSecs or so). Is there a way to revert to Snow Leopard OS?

As the last post suggests, call Apple and order a replacement original disc for about $17. They will ask you the model and serial numbers.
Your retail version of Snow Leopard OS 10.6.3 will not work on that Mac as it requires a minimum of OS X 10.6.7 to boot and operate.
Another alternative is to again borrow another Mac to install your retail Snow Leopard into an external HD or partition, upgrade it to 10.6.8 and then clone it back to a partition on your MBP.

Oh, by all means. Uninstall it using its uninstaller if you have one. Do not install any anti-malware software as it's unneeded with OS X Lion or Mountain Lion.
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper 2.0.1
    2. AppDelete 3.2.6
    3. Automaton 1.50
    4. Hazel
    5. AppCleaner 2.1.0
    6. CleanApp
    7. iTrash 1.8.2
    8. Amnesia
    9. Uninstaller 1.15.1
10. Spring Cleaning 11.0.1

I have purchased MacBook Pro in November 2011. However, Pages, Numbers and Keynote comes as uninstalled in the App Store. How to correct this anomaly.

I have purchased MacBook Pro in November 2011. However, Pages, Numbers and Keynote (pre-installed) come as uninstalled in the App Store. How to correct this anomaly?

If the iWork apps were not originally purchased from the App Store, i.e., you bought them on an iWork installer DVD, then the App Store has no record of the purchase. When updates are available for them, you'll get your updates through the Software Update application rather than through the App Store.

I bought a MacBook Pro in September 2011 and it has never worked well.

I bought a MacBook Pro in September, 2011 and it has never worked well. Are there known issues with this machine? It just stops responding, usually for 3 minutes (especially when I'm working in iPhoto or Contacts). I regret buying this machine. I wish I could just go back to my previous MacBook Pro. Any chance Apple will just exchange this for me without it costing me my other arm & leg?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

It is for the MacBook with built in flash storage.

I bought a Macbook Pro in August 2011, so it has been only 16 months up to now. However, its logic board is broken now. Can I ask 1) where can I buy this mainboard?, and 2) how much does it cost?. Thank you

This is one instance where you'll curse yourself for not having bought the AppleCare Warranty extension and gotten the board for free.
Anyway, get your model number handy and go look up the parts in www.powerbookmedic.com or www.ifixit.com amongst other places. They've also have videos or photo pictorials on how to do the replacement. Not altogether trivial, be sure to spread the adequate amount of thermal paste on the CPU and GPU, else you'll fry the new board in short order again.

I have a macbook pro 13" early 2011 version and what to install windows 7 on it via bootcamp but not sure that whether to install x64 or x86 version? which one will work better

There is no need for anyone to use 32-bit version anymore.
Retail comes with both. Or you can save on just buying 64-bit System Builder disc.
Better support for today's hardware with larger video graphic memory and systems.
Better memory management.

Likely a hardware issue... no way around that except to get it repaired or don't use it (the button).
Try restoring to solve the switching off problem.

I downloaded iOS 5.0.1 to my iPhone and all of my voicemails disappeared except a few from the last week. Are they gone forever or is there a way to retrieve them?

Welcome to the Apple Community.
If you mean you deleted the files from Pages on your phone whilst using iCloud, then yes they will disappear from Pages on your iPad too.
If you simply deleted the app from your phone, if you were using iCloud then they should not have disappeared from your iPad.
It's not clear from your post, which of these you did.

I put my ibook author file in the trash and then accidentally emptied my trash. Is there a way to recover the file? Does iBooks Author have a backup?

if you use time machine, you should be able to get it back that way. Although IBA saves changes on an ongoing basis, it doesn't create a back up or supplemental copy elsewhere on your drive.

I just bought a Macbook Pro and I can't connect my HTC One to it. It's very annoying, especially since I already uploaded my music to the Macbook.

I just bought a Macbook Pro with Retina and I cant' seem to connect my HTC One X+ cell phone to it. It seems that I have to download the HTC software for the phone called HTC Sync Manager, but app won't open on the Macbook Pro because it's "unidentified." PLEASE HELP! I just uploaded all of my music and I really want it on my cell to run to. Thanks!

OK Folks i believe i have actually found the solution. I know i am a bit slow but i only got my New HTC One 32gb today (it was free from Three). Like you it would not connect to my Mac or work PC. So here is the way i got it to work. Download Android File Transfer if you have not already got it. Make sure you have USB Debugging setup etc. Now you need to download a free programme called SyncMate. I used SyncMate 4 because i am running OS X 10.7. There is a paid for version of Syncmate but we just want the free version as it seems to contain some drivers that will make Android File Transfer see you phone. Download SyncMate, install it as per usual and hey presto when you plug in your HTC One Android File Transfer should open automatically...BINGO!!! It worked for me which i am really chuffed about as i was just about to ring Three back up to get the phone returned. Let me know if it worked for you too :-)
Cheers dudes
