Messed up with the Default revisions

Ok, so while trying to change how revisions work I made the mistake of modifying the Default revisions. Now, this would not be a huge problem if it wasn't for not being able to change it back. Whenever I try to save, I get the following error message; Internal Error: the major revision "A" specified for Revision is invalid Highly frustrating. I tried creating a new "Default" revision to replace the old one where it is used but when I try to do that; Internal Error: the major revision "A" specified for ItemType is invalid. I could resort to reinstalling Innovator but I would really prefer not having to take it that far
