IM issues - can barely receive messages
 

Today and yesterday Ive been having serious issues with my IM programs. I use Skype and MSN, and neither of them have been able to send my messages or give me mine with a few exceptions. Both IE and Firefox on my computer works fine. Does anyone have any idea what could be wrong?

Some questions:
What is your firewall?
Do you use a proxy to connect to the internet?

I can imagine that your firewall is blocking it or that you have a port blocker enabled...
