OK, here is my problem now. I downloaded URWIGO to another computer with windows OX and tried my wheriogs on it and it works fine. I can build cartridges fine. BUT I still can't get it to work on my desktop with windows 8 or my laptop with windows 7. It gives me an error that the server was unable to process my request. Invalid username/password combination. I tried turning the firewall off to see if that makes a difference, but it doesn't. I have repeatedly put I my username and password in URWIGO and it is correct. Any ideas?
