Why does StarTools keep throwing "Could not create Tracking data files" popups?

StarTools is a unique piece of software that keeps track of signal evolution and noise propagation. The data it needs to store and access may grow to many gigabytes. As such StarTools uses your storage memory (hard drive or SSD drive) to store this data. If StarTools is unable to write this data, a message may appear alerting you to this.

If this suddenly happens, for no apparent reason, then this may be due to insufficient disk space, or may be caused by some sort of OS-level software component that has started blocking writes. Software that may interdict data access may be anti-virus software or automated backup solutions.

Please not that some operating systems can also put drives into read-only mode if they detect severe drive issues or imminent hardware failure.
