Bought a 2nd hand MBA but now can't download iPhoto

Question

I recently bought a 2nd hand Macbook Air and it already had Lion installed. It didn't come with the Lion USB so I can't do a reinstall if I wanted.
Now when I sign in to the App Store and try to download iPhoto or Garageband, I can't. It says something about my profile not being allowed to download it as the download is attached to another account, presumably the previous owner.
So how am I able to download iPhoto? I don't mind paying for it, but it still won't let me as the only option I get is "Download".
Any ideas would be great.
Thanks

I think you will need to wipe the drive and reinstall Lion after purchasing your own copy from the App Store. I suggest the first thing you should do now is backup anything on the drive you need to keep. Then sign in to the App Store under your Apple ID and purchase and download Lion if that's possible - I think you should be able to do that.
How To Re-Download The Lion Installer
This appeared as a hint at MacOSXHints.com, and will work to force the download of any purchase on the Mac App Store.
Open the Mac App Store.
Navigate to your Purchased page.
Hold down the Option key on your keyboard and click on your 'OS X Lion' purchase link (not on the 'installed' button).
You see the Lion product page. It should say 'Installed,' but that button is clickable. Hold down the Option key again and click on 'Installed.' If you don't hold the option key it will tell you there's already a newer version installed.
Enter your login credentials.
Download.
It's important to hold down the Option key twice. Once on the Purchased page, once on the Lion page. You also can't navigate to Lion directly, you need to open it from the purchases page.
If you follow this procedure you should find the Lion Installer in your Applications folder. Be sure to move it to your Downloads folder for safekeeping. Do not use it to install Lion, rather make a copy to use.
Once you can download Lion you want to keep it and make a bootable USB flash drive installer for yourself:
Make Your Own Lion Installer
1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing Lion.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to several hours depending upon the drive size.
3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the InstallESD.dmg disc image file into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable Lion installer that  you can use without having to re-download Lion.
Use the installer to first erase your hard drive then install Lion:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot from your USB flash drive installer:
Restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the USB flash drive and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
