Can't download 1.51. Says CD Key not valid. any suggestions?? 
enter your CD key then retry
good hunting to all, except when hunting me , then best look behind you cause that's where i'll be
Download or install? You shouldn't have to (and don't) put in a cd key to download a patch. PM me and we can get on Skype or Vent sometime and get this fixed for you.
That sometimes happens to me due to a custom map interfering somehow, or just having too many maps in my folders. Taking out all of the maps, except the ones we're currently using, usually fixes this without having to re-enter the CD key or re-install. Don't know why this works, but for me it does.
