Hi. I recently downloaded the Undead Patch to get all the steam games. I then got the GCF files for Portal, Half Life 2 and Episode 1 & 2. Everything works fine except for Episode 2. I made sure that I got all of the GCF files, but when I check my My Games, the game is stuck at "Download Starting...". Then, when I try to launch the game, a message pops up saying "The Steam servers are too busy" or something like that. Please help!
