1] What are you rendering? Stills? What resolution? Mixed Media?

2] What are your Project settings?

3] What Format are you rendering to? Meaning, what is your final output?

4] What other memory/CPU hungry s/w are you running? Antivirus? Anything Scanning your PC?

VMS is a fine piece of software. It works, and works very well. You should be rendering OK, if your hardware, software and content will allow it to do so. My experience on these matters often tells me that it is the things above which can kill a render. There are many others successfully using this software. Get back here and let's see what it could be that is doing this - yes?
