UGS Platform " Windows Can't Find Target" problem

Been using UGS Platform for more than a year but I have developed a problem. Then I try to load a g-code file I get the error below. It appears and I have to click it closed twice BUT then goes ahead and loads the file. If the needed file is deeper in the file structure I get the double error twice for each level I am moving through.

I deleted the entire preference file and it did not help. I then deleted the entire UGS folder and replaced with a fresh copy but still no help.

Anyone have any ideas on how I can fix this.
