Ok here we go.
So I was trying to make a rig on Paint for the first time (in forever). When I finished, it overridden the original items file. Then I opened up MI...
and the whole script error thing said the items file had too large items and therefore can't load AT ALL!!
Thankfully I have found other item files online that are transparent (phew!) but I can't find the original one for 1.0.6
If anyone can send that to me please do so!
(It's in User>>Mine-imator>>Data>>texture>>items)
