Help57475 : Server Disconnected

can someone help me with this error? eh seen a solution but it seems that in version 17 addresses changed and I can not solve it, there is someone who can help me? would greatly appreciate it

Someone told me to Go to create a class unselect/reset everything and then create one from scratch. Worked for me but you can try http://www.mpgh.net/forum/674-call-d...d-how-fix.html if that doesn't help.
