I am currently running Windows 7 Ultimate, upgraded from Windows Vista. I have the latest updates, latest versions of my messengers, and updated all device drivers, however; two of my programs still refuse to operate... Dell Video Chat (created by sightspeed) and Windows Live Messenger will not run but things like Skype and AIM will. All of the worked at some point in time, and all with the Windows 7 RC and all the updates I've downloaded. I haven't installed any other software to my computer or downloaded anything that I can think of that would have stopped their operating. Both programs open and will start, however, neither will connect. Both services say that they are unavailable with no explanation. I've uninstalled and reinstalled both, removed McAfee, allowed them through my firewall, and everything else I can think of. Any help will be greatly appreciated. Screen shot below is of their error output. If you need any other information, feel free to ask, I'm more than happy to work with you.
