I am having the same issue but I thought it was because I updated to the latest Java. It very well could be Java, I have had so many issues with it in the past, including having to reinstall windows on a couple of computers one time (I think it was version 6) because it crippled them from a glitch.

I tried going back to an older Java version but they make it pretty hard to do and it's only meant for business customers.
