Trouble with Sprutcam

I am trying to work on parts that I had partially completed a while ago. I got back to recently and either can’t open it or get an error. error importing file. Location C:.…_HISTORY.…STC.~33~
There is only one version of the file I can open but I cant change settings like tool number. Whats going on? I’m using SprutCam XV 15

@Arthur_Kanitz1 This may be something you want to reach out directly to Jake about. Jira Service Management I would put in a ticket with SprutCam America.
