Repka 1 had the most players online for 2 days. That is why it is the only one you can not rejoin. Too much data to transfer = more chance to loose something.

Get on Teamspeak or Ventrilo with your friends and ask them if they can join when you can not. After you loose connection try waiting 2 minutes before joining.
