Hello, I have a Mazatrol 640T, which stopped working, I have a registration error and does not start Windows 95. I managed to install a version and everything is fine until I install the Mazatrol Software, I get the file "VNCPD.VXD", I press any key to continue, start windows, start the Mazatrol screen and freeze, it doesn't do more. Any suggestions on how to solve this problem? Best regards.
