Emulator Problem: Games refusing to stay saved

Hey guys,

I have had the emulator for a few years now and have only just started to use it again as of the other night. I have been trying to play Majora's mask, I have gotten upto Woodfall temple, saved at the owl statue and closed the game and emulator to go to bed, and as of this morning I went to go play it for a little bit and my save file is no where to be found, like I had never played the game at all. This is also happening with my other emulation games

What is going on? Can someone please help me? This is very frustrating, this would be the 5th time I have had to restart MM now.

You might wanna try using save states instead of actual saves, but as far as saving goes, do you have any antivirus software or any software in general that might interfere with programs?
