One more issue-5.0 software & BB App World

[sb7]

I updated my software to 5.0. I get notifications on my home screen when an app I downloaded through app world has an upgrade available, which is nice. However, when I try to upgrade it I get a message "(insert app name here) is not available for download from App World." I get the same message for anything I try to download through app world whether it's an upgrade or first time attempting to download. I have deleted & re-installed app world & it didn't work to solve the issue. Anyone know how to resolve this? Any help would be greatly appreciated.

hey there, what apps are you having this problem with? if its all of them then do a security wipe? Go to options, security options, security wipe, when there mark check user applications. Before all that I recommended you back up phone! In D. Manager.
