Why cant open my downloaded apps????

Why i cant open my downloaded apps after i close my phone and reopen it???

I was having this problem too. So I restored my iPhone in my computer and downloaded all again. It worked.

Probably because some file or directory has become corrupt. Restore like axelmusso stated.

If it worked once it shouldn't have a major problem, maybe just a glitch. Try turning it off and on again and see if you can log in. If the problem persists, try reinstalling the apps. If yet again the problem persists reinstall the iOS, and eventually if, god forbid, you still have problems get it to a service to have it checked out.
I hope I helped
