Realnoicepotato

so I was using an older version (like an idiot) for quite a while now, so I decided it would be fun to try out the newest version of mine-imator instead of the old one, so I downloaded it, upgraded, and opened up my old file. But when I tried to save, it just outright crashed! Please if you know why this happened or have any specific questions about what happened, leave a reply. It would help allot!

so i open mine imator and make an animation, than i close out to work on it later, when i open it back up THE FILE IS GONE AND I NEED TO UPGRADE AGAIN

i mean when i open mine imator it deletes the file and i need to upgrade again

PLS HALP i can't save my projects I EVEN UPGRADEd nothing is working, halp
