Restarting your UT would fix that temporarily. Not sure why that would be a blacklisted class however.

Does that occur when trying to join #2, or when joining #1 after joining #2? If it's the latter case, it's bad cleanup and should be easily fixable.

I have today exactly the same issue as Yanriel. Starting UT2004, connecting #2 (Invasion) and then I am kicked out for RBThinkTankVenom.SpiderInteraction. UT2004 restart doesn' help. WTF?
To #1 I can connect with no problems.

Did you extract any of the files from your cache?

Yes, mostly maps.

I have found entry in the cache.ini: 1C5819A24429D2D47629178D1CC1FA76-1=RBThinkTankVenom.u and I deleted it and a corresponding file from cache but I can still view that it is downloaded when I am connecting to #2. Then I am kicked out.

This time I again downloaded it and was not kicked out. A small wonder

i got a new one o_o ...

I rebuilt my character and skilled turret construction...
then i placed a turret which was giving to me 10k lvls (not even xp...) per shot
there were a lot of spam so i quitted
each shot still gives me 10k lvls everytime i join :\

Oh, no, it kicked me again for the SpiderInteraction class reason. I was played one Invasion map with no problems and then loaded another. UT restart not helps. What's going on with Anti TCC?

Oh good god. Yanriel, does this happen whenever a turret shoots a monster, no matter which monster it is?
