Unable to access image file?

Hello everyone,,

I'm trying to mount a .mdf file, and Daemon Tools Lite is giving me an error that simply says "Unable to access image file". The only other thing I've seen with this error message is from 2006, so I'm thinking it isn't too accurate anymore, and there was no solution in the thread anyways.

I'm on a Windows 7 64bit OS, with Daemon Tools Lite 10.2. Any help would be greatly appreciated.

Thanks!
