I have officially given up.
Thanks for the offer of assistance via MSN, but I understand the steps. They just don't seem to want to work on my forum.
I followed your instructions about renaming files and changing calls, etc. from this post:
ibProArcade Fixes
I then changed it all back, wiped arcade out completely- uninstalled product, deleted files, checked that the tables were gone everything..
Then re-installed and tried all of the edits again.
No go.
Thanks for all the work you've done, Hippy.
It just doesn't seem to want to work on my board - even with all other plugins disabled.
All the best.
