font tahoma doesn''t support the character italic

Hi there,

i tried to load unsuccessfully a database(tables) from a trial sql server 2005 i downloaded a couple months ago, the server worked fine before i updated my .Net framework in 3.0(my OS windows home edition XP SP2). So i unistall the Net framwork 3.0 even though i continue to get the same error: font "tahoma" doesn't support the character "italic".

Do someone has please an idea how i can solve this problem?

Regards
