I has a Bukkit Gui v2 and IT Stoppped working for a reason idk like it dont work everytime i click on it it stops working
The issues with the latest version should be fixed (they were caused due to incorrect responses from a server, these errors will be caught in the next version ). You can run the same version again and it should work. Should you have any further issues, post them either on the forums ( http://bukkit.org/threads/40109/ ) or on dev.bukkit.org ( http://dev.bukkit.org/bukkit-plugins/bukkitgui/ ).
