Sorry, I didn't notice the message the first time.
That's a really weird problem. Never seen anything like it before. And you already tried all the things I usually suggest (download version, latest graphics driver, ...). The font used in the game is bundled, so that shouldn't be a problem, if the font won't load the game would crash. Rendering of lines & triangles work (as seen in the background animation and menu background). So I'm just guessing here...
Can you try the following things:
- Can you click where the text should be? Does something happen?
- Can you navigate via keyboard? I.e. pressing enter twice after starting should bring up the "Log in" dialog. Does that work?
- Do you have antivirus software running? Can you try to disable it for a while?
- Can you try an older Catalyst version? Or a newer beta version?
- Can you post what exact hardware specs you're using?
Cheeers,
Simon
