I'll try that when I get home. I really hope that's all it is. I'd rather kick myself for not checking that than have to haul my 65 lb desktop monster around.
Out of curiosity's sake, if that's not the case, is there anything else you can suggest for me to try at the same time as that? Or in the case that everything is "perfect" but still not working properly, is the concept of transferring registration to another 'puter out of the question?
