3D MF & Remix Decks HELP

Recently purchased the 3D midi fighter and having a lot of fun using the effected mapping from DJTT (ref: http://maps.djranking s.com/mappings/614)

I now want to use it to control the remix deck which I must admit I had a few issues getting to work before.

When I load a remix .trak file in it seems to load fine into the Traktor browser window, however when I drag that remix file into a remix deck i get the error message: "the sample xxx could NOT be played due to a missing or corrupt file".
I thought this was just a corrupt file to I tried loading 3 other .trak files from different sources and even created my own one from scratch and I still get the same error message.

Any suggestions? Thanks J
