1.1.3b2 includes some changes to the license validation code to try to make it more reliable. I've had a couple people have trouble getting their licenses to work. Let me know if you have any troubles.
Additionally, as 1.1.3b2 is the first release to use the new beta testing infrastructure, please let me know if you have any trouble with it. I'll update this thread when the next beta is posted so you can see if the beta is updating properly.
