Emulator Problem: PCSX-Reloaded. fine before. now game screen too wide.

i used this to play final fantasy 7 and it worked great. but one day i loaded the game and the screen is now too wide. you can see everything, but its too wide (rectangle) than what it was before (square like) can someone help me? I tried adjusting settings on the emulator and my computer but still having problems. emulator i use is PCSX-Reloaded

They added a new widescreen option, just find it and turn it off.
