Ok I have downloaded all required GCF's (I think) and in steam it just hangs on "download starting" What's going on, I've used GCF's many times before and episode 2 is the only one I've had trouble with. Here is a list of the GCF's I downloaded: episode two content episode two maps episode two materials episodic 2007 shared base source engine 2 episode 1 shared source 2007 binaries source 2007 shared materials I use Undead Patch and also have the original Half Life 2 installed. Also CF Toolbox shows episode two content.gcf as being 99.92% complete I have redownloaded twice and it still shows as being 99.92%? The GCF is fully updated (v9) so I don't know what the problem is. Any help is appreciated!
