The DJ forums are pretty unresponsive these days. Sometimes you have to reload many times before a page will load.
To save you the trouble, here's what I posted in that thread:
"Last night, with some invaluable help from Tote, I successfully managed to install Dundjinni v1.0.7 on a new computer (a MacBook Pro). I also managed to get all my artpacks installed/registered. It all runs great, so I am back in business as far as making maps with DJ is concerned.
The installation procedure was not simple and straightforward, but someone willing to jump through a few hoops and tweak things a bit under the hood, it's entirely possible, and can be done in 30 to 60 minutes. Just wanted folks to know that."
