iTunes store apps wont work.

So i've had my itouch since christmas and suddenly today it won't let me acess the itunes store and app store. it will let me search, but say when i open the itunes store and say click music/videos, it says "your request could not be completed".

help? my wifi connection is fine.

haha okay we'll see hopefully it'll start working! let me know if you find out the problem.
