jQuery conflict with theme

Just upgraded to wordpress 3.4.2 and the plugin I’ve been using for ages stopped working. http://idpturkey.net The sign in register panel at the top.

I switched to another theme and it worked. The theme I’m currently using is a premium Fast Blog theme.

Can anybody help ?
