Should now load correctly. Was a really quick fix. I actually replaced the buff windows with my own as they were essentially the same. I do not know if it is HoT compliant or not, I do know that is loads without errors. The rest is for someone else to figure out.
I did change the primary/secondary with the 9th and 10th inventory slot on the hotbutton window. One could probably fit all 10 slots and the pri/sec on that tab if the icons were rearranged/shrunken down some.
