java.lang.NullpointerException after App World update

I updated BB App World from version 1.x to the 2.10. Since then, App World won't start up.
When I click on the app, after about 30 seconds I get the error message:
"uncaught exception:java.lang.NullpointerException"
I've done the battery pull numerous times. I've deleted, downloaded and reinstalled the app numerous times. Same thing occurs.

Any ideas? Blackberry forums are of no help. Reinstalling the OS is out of the question since it's an enterprise version.
Thanks,

Here is the error log:
