1.75 bricks shipping menu under admin on 1.5.5f

fresh clean install on 1.5.5f with the plugin 1.75 bricks the whole shipping module.

what kind of crap code are you releasing? i understand this is free but if it's bricking a brand new unaltered clean install something is wrong with your code!

if you can't even put out clean code for free plug in why on earth would someone want to hire you idiots to do something more complex?
