Saving problems with vbagx

Hi there. I'm new to these forums, so bear with me if you must.

I was playing a game on vbagx. I saved in-game. I played a little more then saved in-game again. I checked the S-RAM saves on the menu, and it was there. I came back the next day, loaded up my game, and my save file was gone. What went wrong, how do I get my S-RAM save to work on vbagx again (the S-RAM save is still on my SD card in the vbagx saves folder) and what do I do to prevent this in the future? Any help is greatly appreciated.

I personally have never had this issue, however I always load the game from the using the home button on the Wii remote. I don't try to load from the actual game menu. That's just me though.
