Hi, whenever I join a server that isn't my own, It will show the loadin bar, then go to a white screen. The Switch, Reload, all the buttons are still there, but where the game would be is completely white.

Here is more details from the CMD box:

Autodetecting java
Testing default folder
Checking C:\Program Files\Java\jre6 folder
Found java in C:\Program Files\Java\jre6 folder
Starting java from "C:\Program Files\Java\jre6\bin\java.exe"

It worked fine untill I completely reset my computer, but since then, I have installed the client, as well as the latest version of Java, and I can connect to my own server. I am on Windows Vista 32bit.
