I saw there was a "new" effect called OVERDRIVE. I loaded it via GuitarLab and made a test patch. That seemed to go OK. Then when I opened Tonelib, I got an error message saying "check failed" and it never opened. I tried several things, including adding/removing the OVERDRIVE effect, a factory reset, retried the patch - same problem. Is this a known issue?
