What about a server authentication error....anybody??

hey guys just need some assistance plz..Most of the maps that require t4m I have tried and most of them worked on solo and some of them just crashed upon loading solo..I cannot get none of the maps eg.batman to work on LAN..yes we all have the same specs PC wise,we all have the t4m in the correct location,we all have the same version of the map..we are on the same network,the error is 'connection timed out'..any other map works fine..any assistance would be appreciated..thanks

sethnorris i enjoy this map so much it's taking us a while to beat it,I read all the comments and stuff..you said hitler was the beginning and the end and everything is on the map and the hud.you also said your doing updates.my question is "1.is there an endgame?..2 Does hitler have anything to do with it?"

I got everything working fine but when the box is built and I hit it I dont see any weapons and cant get any weapons

So I am trying to add harrys tranzit buildable power and cannot seem to get it working.when i add the stuff from his download into my map i get the error  " animation 'pb_laststand_idle' not defined in anim tree 'generic human'  ".There is also a folder in his download named "harrybo21 craftable v3.0.1" I tried using that and added the tranzit buildable,everything showed up in radiant but only the bench showed up ingame.not sure how to get this working..help!!!!
