[TF2] can't get SCDRS to launch

[frog7227]

at first attempts i reinstalled steam, source SDK ,2006, 2007 and source multiplayer dedicated server and tried to launch it but it wouldn't launch at all except saying preparing to launch but it would say in game then steam would say i was just online again. computer has a Pentium 4 2.66 GHZ (512 KB L2) 768 MB of ddr 333 ram and XP SP3 i don't think steam downloaded it but iv'e deleted all the files in the "steam" folder after uninstalling steam and i reinstalled everything except the OS and still no dice. using the run command with the command line does nothing it just says that the files are non existent
