When I have Solidworks 2009 SP2.0 I kept getting this error message at random intervals. Basically, I would be doing something (random) and solidworks would just crash on me and display this crazy error message in chinese... Then SP3.0 came out and the problem stopped occuring. Now I upgraded to SP4.0 and.... well, the problem has returned and I keep getting that error message again. It is really annoying because I cannot even recover the files terwards. I have screenshots of the error message when I was using SP2.0 and now with SP4.0. Has anybody else received this error and if so, how did you end up fixing it?
