My girlfriend is having this weird problem with her App Store in Windows 8 x64 Release Preview. In the starting Store screen the apps are there (for example the "cut the rope" game), but whenever trying to search for them (either with search function or by clicking on "top free", etc buttons it doesn't list anything besides Xbox Live Games app.

She does already have a Xbox Live profile set up and the Xbox Live app installed (though I have no idea if it is a requirement for anything).

On my laptop (with my account) the store functions normally, but on her desktop she only has the apps that appear on the front page which is annoying.

Does anyone know what's up? I don't recall having to do anything on my laptop for the store to work normally.
