I did. Once I got past it, I finally got the feats linked with powers to successfully drop. Now when you drop the feat on your ability section, the power appears on your power sheet (you may have to expand the node to see it).
Looking at it now I don't understand how it took me so long...but that's life. Oh I also modified magic items so GMs can add their own properties and powers, also so they can delete the existing ones if they so desire.
