If you get an error message about eWallet trying to access a corrupted Century Gothic font on your (Windows 7) PC, then you may find a resolution in Microsoft's forum. The article Windows 7 fix: fonts on the blink also describes the problem and includes instructions on how to fix it.

You may also see a message like, "ArgumentException: Font 'Century Gothic' does not support style 'Regular'" -- that's the same Windows 7 issue as described above.
