Missing Button Text (1 Viewer)

[free_heeler]

I recently re-built my HTPC with Windows 7. When doing this, I had some problems getting some of the plug-ins to work, then found that the text on the majority of menu buttons (TV page - see attached, top bar, showtimes, etc) were no longer being displayed. I have completely re-installed MP but still have the same problem, so can only assume that some fonts have somehow been deleted.

Can anyone help please, as navigating blind is a little difficult.

See my mediaportal.log file attached, showing font calls.
I have also attached the error.log which shows many "no translation found" errors, but from searching elsewhere, I don't these are relevant.

Thanks in advance
Steve
