I have only just installed WW so I'm guessing I didn't configure something correctly. What might be causing this?
Sorry about this issue.
Please explain the exact steps you took to get this error. Also, please reproduce the error and after hitting the OK button, hit F11 to get the full error. Copy the entire message that is in red and paste it here.
Thanks for getting back to me. In the meantime I revisited the set up and reinstalled Steam and source SDK and the files loaded properly, it's working now, I think the gameconfig.txt was corrupted!
Thanks for the info. Glad you figured it out :)
