Shoot. I knew I was forgetting something. Glad to see you figured it out, though.

For everyone else, just download the file on this site and install to your windows/system folder for it to run.

If you can't get the launcher to work, you can also boot the game from the command line:

-sv : server mode, must also be run with client mode to play
-cl : client mode
-ip : ip address to connect to (client mode only)
-level [n] : where [n] is the level number you want to play. only specified if -sv is selected
-pl [s] : where [s] is your name. 16 characters is the suggested maximum.
-dm, tdm, or ctf : the gamemode. only specified if -sv is selected.

Next time I'll remember to include the necessary DLLs in the archive so you don't have to download them separately.

Also, thanks for the feedback, Quadraxas. I can easily do both.
