Ive recently installed Snow leopard and the updates to my dell mini 9 successfully using guides on here (woohoo!)
I have installed messenger for mac from microsofts website but as soon as i try to sign in, it fails. Adium also had the same problem but changing it to "connect via HTTP" makes it work. I know people will say just use adium but i want to use messenger for mac.
Ive tried opening port 1863 on my router (incoming and outgoing) and ive checked to make sure SL's firewall isnt on and none of it has worked.
EDIT: Same thing happens for iChat with AIM, when i change the settings to use port 80 it works instantly..
