KF Problems with some maps when creating listen server

[DanoMonzter]

Hey guys

When I create a listen server (LAN & Internet) for play with friends, On some maps (Not all), they get stuck in "connecting to".
I thought they were custom maps, but this happens with many maps, Even with official maps!
I do not know how to solve it, it had never happened to me, Even before we have played on these maps!
I hope they can help me or give me an idea to solve it.

What mutators do you use?

These are:

Armor regen
Health regen
Weaponconfig
Slotmachine
Kill/damage message
KF2 Pat
KF2 Hardpat
Alltraders
Autorespawn
Autorespawnmessage
Server veterancy handler v7

Those are the ones I use, I just do not understand how it happens with some maps and others do not, I say this because although I delete some, the same thing happens with some maps, Even without having mutators.

Oh btw sorry for my english.
