Boing Bag Boom!?

[adolescent]

I got brave last week and updated my A1200 OS3.9 BB1 to BoingBag 2 and now it won't boot.  It gets through the startup-sequence and user-startup but then just hangs at the loadwb (no errors, guru, etc.).  Any ideas of where to look first?  Are the files that BB2 replaces archived anywhere that I can copy them back?  

System: A1200, Blizzard 060/50+SCSI, 2M CHIP, 128M FAST, 20GB IDE HD.

Thanks for the suggestions guys.

@Sundown

That is my plan, but I need WB to do it.  Unless someone knows the secret password to unpack the update zipfile.  

Also, I installed this system directly from the OS3.9 CD a while back, so there shouldn't be anything "old" on it.

@Crusher

No, I used LZX to unpack it.

@Ilwrath

I'll give the SKIPROMUPDATES a try tonight.

Well, after toying with it for a week, I decided to just re-install OS3.9 and BB1.  Using my premade emergency disk I got everything reinstalled.  The only casualty I've found so far is MUI needed to be reinstalled.  Everything else "seems" to be functioning...
