Have you tried updating your virtual drive program?

The SPTD driver that many of them use has it's own fair share of issues. If you don't keep both updated you stand to run into many of them.

If you have an actual issue with ImgBurn - as in when you're actually using the program/have it open, please tell me about it.

If you have issues with drives and things when ImgBurn isn't even running, you NEED to look elsewhere for the cause. It can't possibly be anything to do with ImgBurn.
