ok i have Skype 4.2 on Windows Vista 32 bit. Skype was working fine with no problems at all but a situation came up and i had to reformat my laptop.
Since the reformat Skype doesn't connect to just one person on my contacts list. Ive uninstalled reinstalled multiple times, even removed him from my contacts and re-added but to no avail. He is on Skype mobile with his phone not sure if this is a prob as it wasn't before.
