Hello Mironidis, sorry to hear of the trouble. The issues you’re seeing are caused by connectivity issues. It sounds like your connection to the game’s servers are shaky, which can cause a lot of different problems. If you’re running antivirus software in the background then please try turning it off and then run AOC as an administrator. You can also check this post I made about connectivity troubleshooting for more tips:
The post is written about SWL, but the information in it applies to AOC as well. Both games use the same ports and have the same requirements. If you continue to have difficulty then please send us an email by going to Funcom Help - Funcom and submitting a ticket using the form there.
