  1. Fix??

while gathering as much info as i could, I looked closely at the error and realized, the issue is in the config file.
renamed config file and allowed a new one to generate.
Now it launches.
Checked the old file looking for a missing key.
The old config file is empty.
Checked the config file on a second computer. Also empty.
Seems at some point, something blanked my TB config files.
Maybe add a check for a blank file, and remake it if empty, but present.

Seems like something wrong happened with config file, in the most cases if config is detected it's not blank, but I will make additional check to prevent this in the next update
