it works on 3.6.x, you only have to change completely the changes in class_core.php as the function name (and how it works) changed
i did it, but of course can't give others the changes to do without authorization from the author... anyway, try to look @ function &execute_query, that's the one to be modified (but of course NOT like in 3.5.x and vbmicrostats 1.05)
