PW games causes Data Execution to kill windows explorer?

insubstantial

I installed Vindictus, another Perfect World title a while back and after adding it to my "Exceptions' list for my firewall it started causing my windows explorer to constantly crash.. due to Data Execution protecting my computer.

I uninstalled that game and did a system restore and it went away.

Fast forward over a year later... after installing Neverwinter... and adding it to the firewall exceptions list...lo and behold.. same problem again.

Anyone have any ideas or insights about this?
