Hello and thanks for your really great and helpful software
I've got a strange problem !
I use x64 build from the official MAME website and I miss one CHD after a scan. The scan is made with the exe from Mame, not from a dat. The only problem is that CHD wasn't updated since 0.133 ! So there is no reason for CMP to delete it...
The error appeared with 0.145u8
I downloaded it again in Pleasuredome, Gametronik... It didn't work. I updated it from v4 to v5, same error.
I looked in the forums and nobody seems to have this error...
I don't understand !

Thanks for the help !
