I have checked your software configuration and I would say that you have a pretty large amount of various low level network software and among other things there is neofltr_600_12507 Juniper Networks TDI Filter Driver (NEOFLTR_600_12507). This can be a reason for software conflict. As you may noticed we try to fix incompatibilities with 3rd party TDI filters (like the latest 2.2.5 release was relative to compatibility with TDI filter from McAfee). Of course the best approach would taking a fresh OS installation and adding software until the problem appears.
