Can't open my project file anymore. Plz help!

Hi, I’ve been working on this cartoon for a month and finally got it done. But today I opened the project to add a little more detail and it crashed. Since then I cant open the file anymore. I think its probably too heavy. What do I do now? plz help I cant afford to lose it. Thanks

P.s this is all in Toon Boom Animate Pro 2.


I was able to open my other projects but not this one. I was working on this project today and it crashed,it gave me an option to save the work before it closed the program. Now The file is too heavey, whenever I open it Toon boom Animate Pro 2 crashed. what do I do now?

I think you should email for help with this one.
