Hi, hope someone can help. I have Verizon 7250 and love the berry411 app. Upgraded yesterday to 4.2 and now can't open berry 411. Get "error starting berry411:Module 'net_rim_locationapi not found"

I have been reading that I need to update my OS server (I have 4.0 now) but since this is a company phone, don't want to mess with it too much.

Tried to download previous 4.1 version and installed desktop software but it only allows me to add application loader files ali or alx, not jad? not too savvy on bb and software, so if anyone can help that would be great. Thanks
