Still having problems with the DMP

I’ve been told to delete the bungie confirmation in order to get acess to the maps, But I dont have a confirmation anywhere on my hard-drive. I downloaded the DMP when I got up this morning. And since then, ive deleted and re-installed both map packs onto my hard-drive with no luck.
Can anyone think of a solution for me?

Try to move some of your LE or P-O content.

There is a more comprehensive thread here discussing the issue and solution.
