I installed Next several weeks ago on a PC dedicated for this purpose. It worked just fine. No issue loading any system's games. I turn the PC on yesterday and no games will load. After running Coinops, everything opens just fine but when any game on any system is selected, the screen goes black and then backs out to the game selection screen. PC isn't hooked to the Internet and no changes or updates have been applied.

Downloaded Arcadia to give it a try and the exact same thing happens. So, I feel like it's a PC issue. Just don't understand why it would all of a sudden not work. Any ideas?

Thanks!
