Pistols raining down from bots creating lag at spawn

[uberskint]

I downloaded de_phoenix_steel map from game banana. Virus checked the Rar pack before I unzipped it. When I load the game two things happen. (1) players joining and being kicked constantly shown on the bottom left of screen. (2) Pistols falling to the floor from every bot, both events creating lag it's impossible to play. Any info would be helpful to correct the problem as I do enjoy playing this map offline for practice.
