SNESx9 Blackout Oddity

Hey all, the SNESx9 emulator was working fine when I downloaded it a few months ago, but recently my television screen keeps blacking out on me when I try to play games. The games still play as I can hear sounds and still interact with menus and such, but there is NOTHING on the screen (aside from the usual "No video signal" from my T.V.)

Does anyone know what could be causing this or if it could just be the settings on my television/Wii? My other emulators work perfectly fine (and I rechecked to make sure this emulator is up-to-date).

you probably have to reset the settings because your tv doesn't support whatever the current video mode is.
