SQL issue, SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '207-0' for key 'PRIMARY'

[ItProbablyIsAl]

Installed Form Tools uneventfully and am attempting to add a form. PHP version is 5.3.29, MySQL is 5.1.73. The SQL error appears no matter if I try to create a form from scratch or attempt to import a form using process.php. I feel like I checked the dumb stuff, but I may not be smart enough to know what's actually dumb. Any assistance or guidance would be very welcome. I've gone through and made everything writable (775 on the files and directories) just in case with no effect. I've truncated all the empty tables to reset the autoID info and still no luck. Thank you for any assistance that you can provide.
