Don't expect the developer to reply to you if the plugin doesn't work. Mine didn't and I've had to start a PayPal dispute against them but they refuse to give refunds even if the plugin doesn't work! 

They have also ripped off other people too. Be warned. I've lost $30 and I won't get it back and have a plugin that doesn't work. 

its a shame that he once again update his plugin and tell every new buyers that it works for 1.8.1 version but its still not works at all and many with me complains but still he try earning money on this plugin and will noy pay back anyone

Marcus this plugin is working properly on 1.8.1 If you are having any troubles please pm me and we will resolve them. It is undoubtedly true that we were on a leave of absence due to some family issues with both members of our team. We are here and trying to resolve any issues you may have. Please send a detailed bug report of the issues you are having along with ftp/site details.
