I had a similar problem with 409m's DGen. There's a troubleshooting in the DGen files at M4T. You're missing some files. I don't understand everything, but what I did, and it seemed to work, was to copy the DGen files from my v112(I can never remember where the decimal goes).
Don't to copy your original DGen folder first for safekeeping. I hope that helps.
