unable to proceed through infirmary door in Tau

[punkonjunk]

Thank you for allowing guest posting. That saves me a lot of time!
I spent some time trolling through the troubleshooting guide, and also trying a few things of my own. full ACL replacement to everyone:full control on all soma folders did not resolve issues, I tried to dig into the included tools and see if I could just remove that door, but I was having a lot of trouble understanding the editor.
So, here is my HPL.LOG: http://pastebin.com/yFp41WKr

Here is what looks like the relevant, and also last, error:

ERROR: Could not find method 'void InfirmaryButtonStateChange(const tString &in, int)' in object '04_02_tau_inside'

Whenever I push the button on the infirmary, the game freezes shortly after. Audio doesn't cut, but rendering stops, and it halts.

Win10 x64, AMD card, yada yada, I don't think my specs are the problem. Would redownloading fix this, or is this piece literally missing? Redownloading will take... so long.
