L4D Survivors and Bloo's Secret Service spawn as if they were statues

[dvaderv2]

So basically, as the title says, the L4D (NOT L4D2) Survivors (even those with enchanced phys), and Bloocobalt's recently-released Secret Service dudes spawn as statues in the all-too familiar reference position.

Looking at the console, it says (using the secret service as an example):
bloocobalt\codmw2\ss_head1.mdl/weapons\w_fists_t.mdl : missmatched parent bones on ValveBiped.Bip01_R_Hand

Any way to fix this other than reinstalling Gmod?

Bump. I tried reinstalling, didn't fix it.

Look in your models folder, if there's files that say "Error" then delete them

They don't have any extra bones do they?

I.E. body armor crotch guards on the AA3 hacks:

Same thing could be possible.

So basically I need to delete a skin for the error model that makes it invisible? I see.
