Hmm, I know this may sound silly and you've probly already done it, but have you double checked it installed into the correct folders, or that no other mod has overwritten/ conflicted with it somehow?
Failing that, if you used NMM, try manual download and just extract it to the data folder, or if you did that try NMM.
