I tried everything I could there, and it worked when I tried to login on an old laptop, but not on my new computer. No idea why though.
I use windows security and firewall and I added PWO as an exception as it said in the link Isguros gave me. I Even tried to disable the firewall but I could not login anyway.Do you have any Firewall or Internet Security products installed on your new computer, or is Windows Firewall enabled? Check that PWO is not being blocked, or try adding an exception.
