Every time I try to start up LW, I get this:



I've seen that other people have been getting this problem, and to fix it they just go back to the previous version of their video drivers. I've got an X800 XT and am now running on the 5.3 Catalyst drivers which were released today.
When I first had this problem I was using the 5.2 drivers so I rolled back to 5.1 but this didn't help.
The 5.3 drivers don't either, and I even downloaded the 4.8 version on LW which is new aswell, but that didn't fix it.

What can I do?
Whatever graphics card drivers I use I get the same problem. I've also reinstalled Java many, many times, but it still hasn't worked.
