.ora files no longer open, 'Programming error detected'

Hello! I love MyPaint a lot and have been having a lot of fun with 1.1 on Linux Mint Cinnamon 17.1. However, I have been working on a webcomic as an Open Raster file and for some reason today, when I went to pull the file up, I got a programming error message. Please help! It would really suck to lose all that work I have been pouring into this wecomic! I am pasting the details of the error message below, any help or tips anyone can give are welcome and much appreciated, thank you!

P.S.- I have tried opening the .Ora file in GiMP as well to no avail.

Programming error message details:

BadZipfile: File is not a zip file

ORA files are really ZIP files containing a number of PNG files and an XML file with information about how the PNG files should be layered.

So the “BadZipfile: File is not a zip file” is not a good sign.

The command line command ‘zip’ can try to repair broken zip files with the -F flag like this:

zip -F Corrupted.ora --out New.ora

This will scan the corrupted zip archive and make a new one eliminating the errors.

If it doesn’t work you can try -FF instead of -F. That will make zip try harder.

It might possibly be that you have to rename your ORA file from file.ora to file.zip, but I don’t think that will be necessary.

I have the same problem however, the error I received is quite different, and it is so long and can’t even post it, so I have put it in a .txt file instead.
