About the error 1054..

Error #1054: Unknown column 'd_meele_texture1' in 'field list'

Notice it says "meele", and not "melee", could it be a typo in the code that causes the error? just a thought.. I'm a n00b to this stuff

In 3.3.1 the npc_types table reverted back to having these fields. Only use 3.3 compatable DB's with 3.3 and this won't be a problem.
