I am still using sony vegas and using it from my c:drive.
The previous year I saved my projects to D drive but I dont see how this could have made the difference.
Still puzzled.. It would seem a bit of a severe move to strip my computer and bring it back to factory state.
I did purchase a large external drive for the system but am not using this to store my movie files on when its time to render them. They are saved specifically on C drive which I triple checked.
