Navigation Screens Broken!

Hey all,

I've got a weird problem which happened recently on my PC. I can't read any of the text which makes navigation a nightmare (going by memory!). I upgraded to the latest release but still the same issue. I then uninstalled, deleted any XBMC folders from C drive, AppData etc. and from registry. Rebooted and tried to reinstall a newly downloaded version and still same problem.

It's hard to explain the issue with words so I'll attach some screen shots of the home screen bar and the shutdown menu to try and explain it further.

I've had no other issues with any other applications on the PC.

Has anyone any ideas on cause/solution?

Cheers,
