Hy guys,

it seems, that i can only join to unmodded official and private server. Evertyime i try to connect on modded server, the game hang up and it shows no loading screen. After a few minutes it kicked me out with the notificiation time out. Anybody got a solution? I already contacted the support, they told me this:

<sup>"please try to completely disable/uninstall your antivirus and/or firewall and
do the following:
1. Exit Steam.
2. Right-click on Steam icon.
3. Left-click on "Run As Administrator".
4. Right-click on the game in Steam Library.
5. Click on "Properties".
6. Select "Local files" tab and click on "Verify integrity of game cache files"
button.
7. Please wait, the process can take several minutes.
8. If the issue persists, reboot your PC and try one more time from step 2."</sup>

It doesnt work.
