Since a while now, I can't use the app store anymore on my MacOS Lion.
It just keeps the screen "One Moment Please. Connecting to the iTunes Store.".
I tried a couple of things … rebootet … waitet for days and tried it again … cleared the cache, as described here: Mountain Lion Doesn't Download from Store and some more stuff.
Nothing shows up in the Console.app … iTunes works just fine …
The only thing that's curiouse is, that if I click on the link "To download iTunes, please click here.", the page shown is in swedish … I've never chosen that as language on this system.
EDIT:
The login doesn't work. The credentials are correct, because I can log in at apples developers area and download stuff like xcode from there.

EDIT: Since you made your edit my answer is not valid.
In Apple store click on Store + View my Account
Sign in.
Bottom right just below the DONE click on the globe flag icon, and change to your country.
