I was over-simplifying in my explanation for the sake of expediency. My use
of the word 'malicious' was to convey a sense of foreboding, not to
qualify/categorize the type of software that executes from the data areas of
memory. DEP doesn't categorize, it simply prevents anything from executing.

This is likely the case, which is why I referred the OP to Pinnacle support.
There is a flaw somewhere in the program that is causing this.

Truer words were never spoken.
