Save Corrupt UPRs
From Ultrafractal Wiki
This happens to me fairly regularly. Generally a ufr file can be saved by removing a lot of rendering info with a text editor and converting it to a upr. Try copying everything from the top line (which should start with 'Ultrafractal', some gibberish characters, then the title and an opening curly bracket, through all the parameter information (could be lots of lines) and include the closing curly bracket. Paste that into UF just like you would a upr.
Best,
Toby
