Problem with MTX Revenant armour pack

Hello,

I purchased the Revenant armour pack last night, but it doesn't seem to be functioning properly. The gauntlets work fine, but none of the other pieces show any pixel detail. Instead they appear flat-grey, or black on my character.

Should I just delete, and reinstall the game? Could it be that simple? If that doesn't work, what should I do?

Please Help.

Thank you.
