Yep, several people have apparently fixed their mars light with the utility. I fixed the fact that I couldn't program any engine for #2, there was garbage in the fields and apparently the Legacy CAB2 didn't know how to erase it.
Too bad about the module, but it would have been a fluke to be able to program it I suspect. I'm temped to pry one of the 1.2 modules apart to see what chip they use, it's not like I'll ever be going back to that version again!
