Hi,
Those errors don't make any sense to me, as they are mainly mentioning this JS file: modules/commonjs/toolkit/loader.js which is not a part of our module. It is something else.
Looks like Flexible 3D Module is conflicting with that toolkit's loader JS. If it doesn't work, then simply don't use Flexible 3D Module. Since, it is a free module, we don't provide free support about it.
Additionally; Flexible 3D Module is made for Joomla2.5 only. Don't install it on a Joomla 3.x website. Find an alternative Slideshow module instead. There are many free slideshow available around, use google.com to find them.
Regards.
