Black Screen

I've previously had a problem with Gigantus' version not going to full screen, so I played around with some files, might have been configurations.ctg. then the game went to black screen with the mouse showing and the music playing in the background. I've uninstalled and installed 2 times but I still have the same issue. Any suggestions?

To get default video settings, simply delete the complete [video] section in the CFG file of RodG.
