Bah, my bad! Uploading! I've gotten rusty.

I'm assuming that when you manually point to the .LUA everything is fine?
I don't know which guide you're referring to, but it looks like some of my old how-to's are still on our old guild site:
http://www.mafiosoguild.com/page/show/23248Note, I don't think I even have an account on that site anymore, so that info is probably pretty old, but before I left that information worked flawlessly.
If this is something that you still can't get to work, I'd honestly consider submitting it as a bug. I'll call some of the people I used to play with and see if they've run into the same thing. If so, then it's probably a bug.
Thanks,

EDIT: Also, and for the record, I seem to recall that in-game you could perform a /script reloadui(), and your in-memory DKP info would then be saved down to the .LUA file. So, in case you crashed, you could still manually upload DKP before you launched WoW again, and upon launching you'd be current. I wanted them to put an option for it in the MOD but I don't ever know if they did. Not that this is entirely related, but I've got tidbits of knowledge making its way back to me now.

Next thing you know I'll be in a guild rocking the DPS charts as a feral druid, again.
