Frequent crash on playback LPX

I have next to no problems with LPX. This weekend, after nothing that I can think of has changed, we had a pretty rough weekend. I'm getting two different crashes VERY consistently. This is one of the crashes. Just on playback. I happened to be scrolling this time, but that really shouldn't matter. This crash log isn't telling me a lot. The other one that I get is involving something called CVDisplay Link and is occurring around thread 78. I can't get this to stop happening. Any help would be much appreciated. This of course is after fresh restarts and all of the easy fixes i can think of.
