Collectible Card Game Headquarters

I have been trying to connect to one of the servers for 3 days now, I was able to get in once and after that I was not able to even host a local game. Yes, I have the latest Java installed on my Windows.Here is a screen shoot of the "error"

Screenshot links does not work.

1) You can delete all files in ../mage-client/db/ and try to reconnect.
2) Your local firewall can prevent you from connecting (no free ports message).

Write the error message here you are getting or repost the screenshot link.

Servers were up the last three days, so it's a problem of your system/connection.

Deletion trick works, thanks mate!
