3.6 has not been released ("soon" is all we know). You should be using 3.5.1, however (this thread says you are using 3.4.1 - perhaps that's not correct?)
At any rate, for plugin help, you need to go to the plugins page (via here http://wordpress.org/plugins/ ), click on the support tab and scroll down to make a new post on the plugin's sub-forum.
For plugins/themes not downloaded from this site, you need to contact the vendor/developer - as those aren't supported here.
