App Store Update Problem, help!

I can't update some of my apps. For example, I could update AIM and Facebook. But now, no matter if I delete the app from my computer and from my phone then try redownloading Pandora and BoxOffice. They are Version 1.0. I've tried anything. Help would be greatly appreciated. Thanks in advance!!!!

 

there are a lot of bugs right now with the app store, i've had the same problem with other apps, i just stopped trying, and will wait for apple to fix the software
