Well I'm glad to see I'm not the only one with this problem.

I was just searching the Steam Forums looking for similar problems. I did find a thread with the same symptoms but he didn't mention whether he uses metamod.
Below is what I posted to that thread.
I've got the same problem... i.e. when my listenserver tries to load a map it crashes to desktop.
However..
I do have installed, and have been using, Metamod117, AMX96j, and PodBot2.6mm. Previous (2 weeks ago) to PodBot I used IvpBot with AMX et al. No problems.
Since the update..
I can use IvpBot withOUT Metamod and AMX
I simply can't use Metamod and AMX
I cannot get PodBot to work, but then again I've only successfully used it with Metamod as it's designed for.
Listenserver without bots or metamod/amx is fine.
Thanks for any ideas.
