Hi Mike,
When I first got SprutCam and had a few tools assigned to TTS holders I went in and filled out my tool table in SC and I had put some fancy long descriptions in the tool table with parenthesis and got the same error. I went back in and edited the descriptions by just opening the perimeters window, go to tool and select the tool I want to edit, change the name or what ever and click on replace.
Seems to me I remember Eric had done a video on the tool table. The video had a section that told where the file is located on your hard drive and how to back it up.
HTH,
Gerry
