These are all the same error. They do not correspond to any known product. Once again, I place the blame squarely on tight pants.
Nope, the real blame is USER stupidity and total lameness. I found my problem. Somehow when I updated Risky WooHoo the Tuning file got moved instead of deleted.
Comforting, really...I
know I can be an idiot, but none of the hackers whose stuff I use is anything less than brilliant. So while it's humbling to have made (and have to own up to!) such a dumb mistake, it's reassuring to know my confidence was not misplaced!
Thanks for all your help, everyone.
