Can't connect to Flash Game - Error #2014

Hello,

www.fuchstreff.de is a Flash Player based card game. When I try to connect to the server, I get the Error # 2014. This Problem startet with the first version 24 of the Flash Player and continued to happen with the following versions.

I use a Win 7 Notebook with the latest versions of Firefox and Flash Player.

Using a MacBook with the latest versions of Firefox and Flash Player causes no problems.

Anyone here with good ideas?

Thx in forward.
