Skype does currently not play well on ubuntu. A work around in your current situation would be to kill all running skype instances e.g. pkill skype
or killall skype
and then launch skype again.
If you want to avoid this in the future, don't close skype, just minimize it.
As an alternative, you might want to try the skype wrapper as described here. As far as I know, this wrapper should be able to handle your situation as well.

The solution is to run sudo apt-get install sni-qt:i386
and then restart your computer. You will have an icon of skype in the top bar of Ubuntu, where you can reopen it and also you can see the amount the unread messages!
