Multiple posting serves no purpose.

A JVM 102 means that the operating system is corrupted.

Downlod the latest handheld OS from your carrier.
Install it.
Get a copy of "Javaloader" - search for it here.
Unzip Javaloader. Connect your BB (Desktop Manager should not be running)
Open a DOS prompt, navigate to where you unzipped Javaloader and type

javaloader -usb wipe

That will completely wipe out the BB. Everything.

Then restart Desktop Manager and it should reload the OS.
