Virtual Cd Hide Problemo

I’m sorry if this has been asked before, I didn’t find anything on the search…
I recently installed Virtual Cd hide to hide my virtual drives. The problem is that I keep getting the message Can not unlock Drive D: (My virtual drive) resulting in me unable to hide my virtual drives. Can anybody help me?
:doh:

Use Deamons Tools. Virtual CD is ok but it has some probelms. Also use this to hide your virtual drives.
