NESten Save Files

[Minunlike]

For some reason, NESten won't load my save files (with the .SAV extension). When I open my ROM and try to load my save file, it says the .SAV extension is not supported. It worked fine before, so can anyone tell me what's wrong?

environment is complicated to say how this happens but it can have a series of factors that would have corrupted the file.
