Is this what you are looking for? Looks like the 2.09 version included a change which Made it work on 5.6 atleast, maybe even on 5.005?, so that may be what was causing your problems.
Thanks, but not quite. I was looking for the changes between 2.06 and 2.07, as these are the versions which aren't and are working, respectively. I tried moving the newer version (2.07) onto the older, but the newer version doesn't like to play with the older version of Opcode. Thanks again for the link.
