Epsylon66,
If you downloaded the latest from the URL then that is in fact a good thing. The file name does matter greatly to the developer (the cat on my end) with the DOM Debugging tools. I would strongly suggest you rename the file to mootools.v1.11.js. I am very surprised, almost shocked it was not named that way when it came down from mootools.

The I would turn "Off" _script_ include on the moolet, as you have the mootools file in the head of your template. which is also a very good thing. Then with the second file include gone your errors should go away.

If they don't let me know and I will go back and check.
