Mod_LoadBrushModel bug while testing

[Sieni]

I made a map and I sent it to my friend for him to test it.

It says:
Mod_LoadBrushModel: maps/mymap.bsp has wrong version number (0 should be 30)


In my comp it works fine

Where's the problem?

He doesn't have the right version?

What is in the map?

good luck trying to get support here... your guna need it...

If he's put anything custom into the map, that would be the problem.
