Try grabbing the latest update in case the crash was something that was fixed since the release (don't think so but doesn't hurt to try): https://sites.google.com/a/webpagetest.o...est-Agents

Otherwise, do you have antivirus or something similar running that may be getting in the way? If so, try and disable it to see if that's the problem (I use Microsoft's security center and a couple of others and it does work but there are some that have had issues).
