I just tried out DropTeam and ran a dedicated server using the command line example in the .PDF file.
I tried connecting via DirectPlay to 192.168.1.100 (and noticed that numpad data entry was disabled btw) and got the following error:
Your username and password do not appear to be valid.
I JUST registered a new account via the in-game account screen and received no error. If I try to create a new account with that username, I get a 'username already in use' error.
Any ideas?
