game freezes upon closing down

[PerfectLyon]

with the addition of the new patch to a our beloved discovery I went about patching the game to get it out of the way. Upon closing down the game it froze my computer to the point where my antivirus removed the .EXE file outright thinking it was suspicious activity. I have never had this issue with any of the previous versions of discovery.

I went about reinstalling discovery a couple more times and each time when i exited the game it would freeze up my computer rather badly.

Is anyone else having this issue or is it just me? If so can anyone lend me a hand here in trying to fix this slight issue
