Apple Event: May 7th at 7 am PT
I upgraded to Snow Leopard and now have the App Store. I was trying to buy Lion, but it wouldn't work. Then I tried "buying" a free app, but the same thing. When I click INSTALL I get the dotted circle up on the gray toolbar but nothing happens at all. I am signed into my account which is all in order. I don't have trouble buying music, etc. in iTunes. Just can't buy anything from App Store. I just downloaded the 10.6.8 Combo & restarted but still nothing.
So use my Snow Leopard disc to reinstall?
Yes.
As with any installation, make sure and backup your important data first.
I did it. Now, in the bar below there is a Question Mark for the App Store (not the A logo) and it won't open.
After install it told me that to use DRM Mapper I had to install Rosetta which I did and it was done successfully. (Whatever that means?) It did that the last time too but I don't think I installed it. However the A wasn't missing last time on the bottom.
Before you upgrade to Lion you need to know that you can't run PowerPC apps on v10.7. Which means you can't use Rosetta.
Read here > Lion upgrade questions: Apple Support Communities
Drag the ? off the Dock straight up.. it should go poof...
Now to the Applications folder and try launching the App Store from there.
DRM Mapper... might be incompatible with using the App Store.
What is Rosetta?
and what is DRM Mapper?
It allows you to run PowerPC apps on an Intel processor.
What is DRM Mapper... it does not come pre installed on a Mac. Try Google.

App Store isn't in applications
You need to take your Mac to an Apple store or Apple certified repair shop.
Most likely third party software causing a conflict. Hopefully they can completely erase the disk and reinstall for you.
Excuse me I have a problem but I can't figure what it is
Can't buy apps in App Store?
