I have heard of others curing this by logging into MyWorld using their PayPal credentials.
I have also heard of others curing it by reinstallling AppWorld:
1) Remove AppWorld from your BB (Homescreen > Options > Advanced Options > Applications) -- if it requests that you reboot the BB, do so.
2) Do a Batt-Pull reboot as described above.
3) Get a new link and install a fresh copy of AppWorld
4) Do another Batt-Pull reboot
5) See if it now works.
If none of that works, then please return to these forums
