I know some people are having trouble with your set up 4.12.11 with Java 1.6.1. I have the latest Beta version in which you can also have if your Pro hasn't expired. Good for only 6 months of updates and e-mail support. Go to support and enter your e-mail address and upgrade to the latest Beta version. I don't think that it will make a big difference though. 10 hosts isn't bad.
