Pokegen crashes after save

[Tommy Tekkno]

Saturday night I was editing pokemon. Loading the save files then re-saving it. It worked great. Did the same thing today. I changed what I wanted changed no issue. I save and the program just quits. It didn't do this yesterday. It won't save so it's crashing before it finishes the process. I've restarted the computer and tried it again. It doesn't matter what method I use to get the save in it just crashed and I have to reopen it. What can I do to Pokegen to keep it from just quiting? Thanks
