I'm currently trying to migrate my test version of confluence to another machine by using the back up and restore method out lined in the wiki, and when I try to do setup from restore it hangs on just starting. The only clue I have is the 'error on page' indication in the bottom left hand corner. Please see the screenshot below.

Key points in my scenario are;
Moving to the same OS
I'm currently on the trial version
I'm going from confluence 4.3.1 to 4.3.3
I'm also switching databases from postgre SQL to mysql
My xml back up file is 6.5mb
Any ideas would be greatly appreciated.
