Bootleg Message

For the last day or so I have been getting a message when I access Draw or Photopaint

It tells me that my copy of the software is a bootleg and several features have been disabled.

Since I am using a purchased and duly registered full copy of X7, this comes as a surprise. I tried cleaning out my temp file directory, and it didn't help.

Does anyone have any idea what may be causing this and how I can fix it? I am losing valuable work time.

Using Windows 10 BTW
