You want the VPK file from episode 1, if that helps any. You also only want models, textures, sounds and particles! Try extracting using GCF Scape. This is really all I can tell you, Tried this a few times and it worked every one of those times.
Sorry for the inconvenience!
Try downloading a program called GCF scape from Nem's Tools. Use it to extract the .VPK files from Hl2 episode 1 (These are the files that seem to cause problems for some people). They should be in /common/half-life 2/episodic or some such. You want the file that has "dir" in the name (episodic_dir or something).
When you have opened it with gcf scape, right click where it says "root", click extract. Extract to some location, does not matter where. Then move the following folders from the newly extracted vpk file to your hypomania folder: models,textures,sound,particles. This worked when I replicated the bug on my computer.
Sorry for the inconvenience!
