I've been using Iron portable for over a year without problems until now that it just won't connect to anything, i keep getting "Error 104 (net::ERR_CONNECTION_FAILED)"
I don't remember making any changes to my computer. I checked for viruses, checked IE's proxy settings, disabled the firewall (the one that comes with XP), disabled the Antivirus (Avast)... nothing.
I haven't noticed any problem with other software, Firefox and Internet Explorer work okay.
I tried installing Google Chrome and it won't connect either. Google Chrome Frame does work though.
Any idea how to detect what the problem might be?
