Won't let me log in to the app store or iTunes. tells me there is an unknown error.

Question

yep it won't let me log in with my Apple ID and password. my apple ID works fine with icloud and logging into the apple support community. I reset my password to see if that helped. it didn't. I tried to empty the cache.db file from the appstore folder in my library. that didn't work. I tried restarting my mac. that didn't work. So I guess I'm pretty much screwed...
I've had this computer for only two weeks and I can safely say i'm not impressed with Lion OSX 10.7.2
There are a lot of weird kinks and issues. Also compatability issues with apps that have worked on macs for a long time.
1.One example is the SSH client Fugu which is just now releasing a preview of the version for lion users (the full version for lion is still not out yet). Why is it that Lion was released before the compatability issues with major third-party applications was addressed?
2. Another issue, VM fusion newest release with the newest update STILL doesn't provide migrate pc for Lion. only the parallel operating system service works.
3. I can't find any internal files with spotlight without bending over backwards. although after bending over backwards i still can't find anything. for example, I wanted to search for a .plist extension file. In the old days you could set your search preferences so that if you wanted to see hidden or sensitive computer system files you could set it to allow this. Same on Pcs. Now, you can't. You can set preferences in the system preferences to look for certain things in certain applications....but there is no way to simply search for files. You can't find application folders and look into those. Nothing. It's all hidden. heck, it took me over a week or so just to be able to find the Mac HD. that used to be on the desktop. not anymore.
4. Wanted to download the xcode developer tool from the appstore the other day. tried to do that and it lagged forever. didn't tell me at what percentage it was downloading. nothing. then I noticed how many GB it took in space and also the numerous one star reviews saying how the newest update had ruined the application and not to waste my time. Why can't we find archived versions of applications so that in case the most recent one is totally messed up, we could at least have the opportunity to go back to the old version?
5. logging into the appstore the first time it wouldn't even let me download a free app without putting in my credit card information. not exactly reassuring after hearing about all these credit card frauds going around that are found to be connected with appstore CC info.
I am seriously thinking that I should either go and get a copy of snow leopard or just return the computer entirely. I haven't been able to get any of my school work done because of all these weird problems. at first i thought it was because I haven't used a mac in over a year.....but now i'm thinking there are issues over at the apple software development team. I hope that apple will get their act together and release a major patch to fix the problems with Lion. They owe it to their faithful customers. please don't turn into another microsoft.

Answer 1

I have decided to dedicate this thread to the wonderful errors of Lion OSX. Each time I find a huge problem with Lion I will make note of it here.
Today I discovered a new treasure of doggie poop in Lion. No Save As......
I repeat. No Save As. In text editor I couldn't save the file with a new extension. I finally accomplished this oh so majorly difficult task (because we all know how difficult it should be to save a file with a new extension) by pressing duplicate and then saving a copy of the file with a new extension. Yet then I had to delete the first copy and send it to trash. And of course then I have to secure empty trash because if I have to do this the rest of my mac's life I will be taking up a quarter of percentage of space with duplicate files. So this is the real reason they got rid of Save As: so that it would garble up some extra GB on the ole hard disk.
So about 20 minutes of my time were wasted while doing my homework and studying for an exam because I had to look up "how to save a file with a new extension in  mac Lion" and then wasted time sitting here and ranting on this forum until someone over at Apple wakes up from their OSX-coma.
are you freaking kidding me Apple? I mean REALLY?!!!! who the heck designed this?!!! I want to know. I want his or her name and I want to sit down with them and have a long chat. and then I'd probably splash cold water on their face to wake them up.
I am starting to believe that Apple is Satan.
