I had to update the queryobj.php file to get this fixed. I also updated your main page to fix the way the code was pre-populating. I think it is working properly on the live site now, so you can download those files for your reference.
I've just updated the extension so if you reinstall it will use the updated queryobj.php file. I haven't fixed the issue with the old version's code being added yet, but this should get you up and running until I'm able to do that.
