I realize I can't post the script for all to see and copy, but I remember reading a post where someone here actually created this script for the company I purchased it from, I think, and if one could tell me which lines to edit if possible it would be greatly appreciated.
It was me... and it's not that simple to convert, either, because you have to get rid of a whole mess of crap, alter loads of lines and then make sure it's still working properly. Absolutely your best bet is to ask them to give you the original version they had - which they've still got. Since you've paid them, I can't see why they shouldn't do this for you.
