So I lost several drawings as well as older files bc they were simply open in SAI at the time and they all got corrupted.
I couldn't find any solid answers to the issue, I'm freaked out so I'm backing up my stuff on a hard drive and then formatting the whole computer.

Anybody have any idea what might be going on? Searching suggested that it was bc of PSD files, but it stopped saving SAI files and THEN I switched to PSD files and there seems to be no answers as to why it'd start fucking with SAI files either.

A friend offered to buy me SAI 2 but... I'm nervous about using a new program, and all my works in progress are SAI 1 files.
If anyone has any advice about how to potentially save corrupted files or how to convert SAI 1 files to SAI 2 files, that'd be awesome. ;w;
