physical properties ice/super ice is not working?

I wanted to build auto-gunshop with physical properties ice/super ice… but it’s not working, doesn’t do anything. Help? (And yes, tested from single player and multiplayer. I’m sorry if i has bad grammar)

Judging by the sounds, something overrides the default physical properties in your game, like pirated CS:S content addon.

Um, other server wont work…

Well, then those servers are affected by the same problem.

You see, it clearly works on a proper set up.

Okay thanks, i got it.
