Hey Vic-Dog,
If you've converted your TF2 install to SteamPipe today, you have to make sure to put the reserved slots scripts in:
"C:/path-to/Steam/steamapps/common/Team Fortress 2/cfg"
If you are using the old donor script verion, the commands you need to enter in console in-game are:
exec payload1.cfg --> Payload
or
exec payload2.cfg --> Votation
I highly recommend getting the updated scripts from the Donor Information Thread (http://hyperiongaming.org/index.php?topic=295.0) (Donors only). I've also updated the thread to be compatible with SteamPipe and added a new method using desktop shortcuts.
If you're still having issues, let me know.
