Segmentation faut error in armcc.exe

Hi All:
I was using uVision 3 with the RealView 3 'C' compiler without problem for a while... Suddenly, I got an error from the compiler:

** Segmentation fault

and I got an unhandled win32 exception from the armcc.exe program.

I desintalled and re-installed the programs again, but the error still there...
It would be a hardware memory error?

Thanks;
Gus
