Ok quick update.

I've just installed dev version ending .062 on my win7 32bit with 2010set and it works fine in both PP and USB SS and purelogic Ethernet. Followed your exact actions in the video and works fine.? Tried to break it by usig different combo's and still it's stable.

So maybe you have an issue on the machines your running.? Maybe some other software is conflicting.? The machine I've just tried it on here is my house laptop and it's loaded up with all kinds of crap so not optimised in anyway.!!
