For the past month or so, I haven't been able to receive any files send to me by my contacts. The files seem to stop after a certain percentage of the file has been received eg: stops after 200kb of a 1.2mb file but only after 2mb of a 10+mb file. To me, the program reports that my contact has cancelled but my contacts sees it as if I cancelled the download. Downloads of any other kind(non-MSN) work perfectly. I've used Adium, AMSN and MSN Messenger for Mac and they all have this problem. It hasn't always been this way and I even tried using Time Machine to restore Adium to it's state at about 1 month ago but it does not work. I've got this problem when using a USB modem, ethernet(to router) and Wi-Fi. I've also experienced this problem with two different ISPs and so I think it's a problem with Leopard? I'm running 10.5.5 on a 15" 2.4ghz Penryn MBP if that's of any help. Any ideas on how to fix this would be very much appreciated.
