Forums mIRC Help Unable to connect to server (Invalid argument)

There is a topic about this but i didn't find a answer there.

What does "invalid argument" mean?
I get this message the last few days.
I can't connect to any server at all.
I checked my firewall and have not added any addons.
I have been using this script for years.
Also a new fresh folder with only mirc.exe will not let me connect and gives me the Unable to connect to server (Invalid argument) error.
I hope someone can help me out.
