I had something similar happen yesterday. Have you checked BD W8 Security Events ----Antivirus---Vulnerbility to see if there is anything there? Yesterday on my W8 computer BD W8 Security blocked what it considered a malicious process on my computer and closed the program that was running the process. After that BD W8 Security would not allow me to open the program unless I approved it in BD W8 Security in the Vulnerability section. I suspect the process was trying to gain access to a port that it should not have. I just uninstalled the program which I knew to begin with was a high risk program and everything was fine after that. Gaming via the internet garners a lot of bad stuff.
