Multiplicity, Fences and terrible weekend

I was using Multiplicity this weekend to copy a bunch of my files from one desktop to another (super cool feature by the way) and it locked up on me. I waited for a while and as the screens grayed out on me. I wasn't able to task manager to stop anything either. Long story kind of shorter, I wasn't able to get it to post for a while. When I did Multiplicity was giving me an error that it had basically disabled itself and I had to reboot to get to work again. This error kept on repeating and repeating so and I couldn't get it to stop. I ended up uninstalling that and having to reboot.  Everything was good when I got it booted back up. I started to then get this error from fences video and a picture this repeated again and again 30 mins before I uninstalled Fences as well.  I am not sure what was going on. Any ideas how to avoid it? after restore my computer?
