I just sent an iCard to my girlfriend using this Win2k machine and IE. So this error doesn't make any sense, in that iCards part of iTools does not appear to check to see if you have a Mac. So why did you get this error? hmmm.... are you sure you clicked on the right thing? Don't get angry if you think this is a rediculous question, or if you tried multiple times to get this to work, I am just trying to help.
