Everything crashes after Glest finishes.

[Sawyer]

Running Glest for first time it runs fine and exiting is fine without any errors, but if I try and go back into Glest or any OTHER game I receive a message and desktop freezes.  

Heres the Crash.txt:

__________________________________________

above was after about 4 crashes.

I am on a Win98SE
               AMD 1.5
               geforce 3
               SB 128 audio

I keep my system pretty well maintained.  
I think it may have something to do with my sound, maybe too old of a card.

any help is appreciated. Thank You....
