Hello,
Here is an explanation and potential fix (curtesy of @crinrict I believe):
"This particular error is the result of a conflict with a program installed on your Machine. It is recommended that stop/cancel all the extra programs running in your computer before starting the game. Furthermore, make sure your internet connection is not running through a proxy.
Go to Internet Options in Control Panel > check the connections tab and make sure the proxy server is not checked. Check the internet settings again and you should be fine."
I would check the usage of your memory (or 'RAM'), as the imperfections of using Bootcamp can cause excessive uses of RAM by certain programs, so watch out for any programs that are using up too much memory. Also, close down any applications or processes running in the background that are not needed.
I hope this helps and keep simming,
Cody
