yes, games are all playing fine if I use a command prompt and play MAME. It seems to be happening only when it trys to play a preview video and there is no video file present. I confirmed this as every time I pointed to the game "600" gameex would crash. I looked in my video folder I use for game previews and there was no "600.mp4". I then copied a file, and renamed it 600.mp4, and the crashing stopped, until I scrolled to the next game that had no video file. By video preview file, I mean the video that plays on the left side of the screen when you point at a game in the list. It also is crashing every time I point at the game Gaining Ground rom name gground video name= gground.mp4. this video file is present and gameex still crashes, so now I'm even more stumped. I got all my video files from emu-movies MAME [Videos][MP4][480p][MAME .144][EM 20111208][WIP] . Thanks
