Though power auras classic is 'outdated' I have 'load outdated addons' ticked. And scorchio is up to date as I get no such message so at the very least scorchio should work. =/
edit: disabled scorchio, logged in & out, enabled scorchio, logged in. Now it shows up... weird...
Power auras classic is still nto working so I'm guessing it's because it's outdated.
Well i'm happy scorchio works atleast
