Ok, so I was in the middle of upgrading to 4.2 when my PC decided to be stupid and restart itself...I was watching TV, and turned around to see it booting back up. My Blackberry was on an whitescreen with the hourglass. Several pulls of the battery later, it finally moved on to a new hourglass, and the Desktop Manager started asking for the PIN, so I let it sit. Then, the Blackberry went through the setup screens, which I followed. Got in, and found most of my 3rd party apps on it...however, NO CONTACTS OR MESSAGES OF ANY KIND. My PC must have restarted while loading 3rd party apps, but before restoring data...so...is there any way to find the backup on the PC and restore my data?

PLEASE HELP!!!
