Simple. Last time I looked Vue was not a operating system. Make sence now? Your using several programs all at once to get the job done and the one that using the c drive is having a problem. It don't have anything to do with Vue. Well not exactly Vue is requesting room for the job at hand and the operating system is saying NO BLOODY WAY. There is no room, OUT of MEMORY even though it's not out at that point. It will be if you try.
