It's possible that you simply got hit by one of the known bugs in 2.0b3.

If it's still working for you, great, keep on using it. If it fails on you again, try downgrading to 1.03 and see if everything returns to normal. If so, leave it on 1.03 until the next 2.0 beta is out where many of the bugs will be fixed.
