Font 'Verdana' does not support style 'Regular'. at System.Drawing.Font.CreateNativeFont()
This error is caused by one of the fonts becoming corrupt within the Operating System. It has also been assumed Office 2010 could also remove one of the fonts.
Go to C:\Windows\fonts to reinstall the font and fix the problem. If the font reinstall does not work, copy the font files from a different machine that does work and place them here.
