working around recent ep2 updates news - Swarm mod for Half-Life 2

Having Trouble starting up the mod? Getting the "SetupArrayProps_R:arrayprop'(null)'is at index zero." error?
The recent update to Episode 2 has made the mod crash during start up. To continue playing you will need to edit the gameinfo.txt file in the swarm folder. The SteamAppId needs to be changed from 420 to 218. Your gameinfo.txt file will need to look like this to play the mod. Also make sure you save the file then restart steam for the changes to take effect.
