WotLK Game freezing upon changing resolution

[MintyPants]

Hey there, I could do with some help!

This morning, I was playing on the Wrath servers, then exited and shut down my computer. Now when I try to get on, I try to change my resolution, but the game just simply freezes in the 'Video' settings tab. Any help would be appreciated!

make sure that your pc will support the resolution that you trying to change it to.

otherwise i suggest you try manually outside of the game itself by following these steps .

1. Open the WTF folder.
2. Open the Config.wtf file using a text editor, like WordPad.

3. Locate the lines:

SET gxResolution "800x600"
SET gxRefresh "60"
