Crashing is usually due to using Java 6. Please ensure you have Java 7 installed, and go to Add/Remove programs and REMOVE Java 6. Sometimes, installing java 7, but leaving java 6 installed can leave 6 as the default still. You should ensure java6 is removed from your system, as 6 has a lot of crashing issues.
Well, it crashed me as well. Wasn't a Java issue necessarily. But it did disappear. I am sure it had something to do with Redstone - just no idea where Correction... Lag is back. Going to figure out where. kitten - don't go back to that residence unless you want to crash again
