GPS stopped working?

[vwman18]

Yesterday I couldn't get a GPS fix on my Vogue. I've been using the leaked ROM starting back in May and upgraded to the official ROM right after it came out and it all worked great. Now the GPS functions don't work anymore. Garmin XT, Google Maps, and MS Live Search no longer can get a GPS lock. I re-ran the PPST file in the windows directory, checked the gpsmode=4 setting in the registry and have soft-reset numerous times. Nothing has been added to the phone since I got it set up with the official ROM initially. Outside of a hard reset, I think I've done everything to bring GPS back with no luck. Anyone got some ideas?

Its a good excuse to go ahead and use the PPCKitchen, I know, but I'd like to get the GPS functionality back in the meantime. I haven't backed up recently and I need to get some other stuff together before I want to wipe the phone.
