Vegas shuts down - this ever happen 2 N.e. 1?

[gullyjewelz]

Whenever I start mixing and editing, Vegas works fine when I add compression, graphic EQ, noise gate to a Bus for several tracks. However, by the time I add additional effects either to the same Bus, a second Bus, or to individual tracks - like paragrahic EQ, a 2nd graphic EQ for extra "warmth", and chorus . . . . Vegas still works fine - if all im doing is editing, mixing the tracks.

However, if I need to record an additional track - after adding all these effects - Vegas shuts down as soon as I hit th record button. And, when i re-open Vegas - the restored version of the file Iwas on is available - but t still will not record.

This ever happen to anyone?
