l4d model problem

after i downloaded Machinima Model Pack v1.zip-

The machinima models were like the one in the photo below all the time, and when i had the folder in my addon folder nothing worked. When I deleted it, everything worked fine except for my L4D survivor models.
I cant move them, but I can still bump in to them.

If anyone knows problem, it would mean a great deal to me if you told me :smiley:

bump, i really need help with this one
