I just had this start happening yesterday
I am unable to chat, send tells, etc. also. The funny thing is that this is only on RK2, all the above works ni problem on RK1. I have also lost my friend list as well. I am running XP and before yesterday things where working ok (even after the patch things where ok, chat just stopped working while I was in the middle of a mission). My friends can not see me as being on either. I am also unable to access the RK2 java chat client now as well, RK1 works just fine. Someone please help me here.
