Here's the deal:
The old launcher is the one that supported P1999 - Due to the Launcher being DOS'ed (Attacked) because of P1999 - it was shut down because it was affecting the newer launcher that is currently in BETA. The newer launcher does not support P1999 because it has a proprietary method of supporting files that is not implemented in the newer launcher.
This is something that Rogean needs to take up with Rumzuck - post this at
