I had exactly the same problem. My old computer did not have enough memory. New computer, problem solved, works like a charm.

Hello,
I downloaded and installed the Nik suite into LR5 (running on Win7) and the only things that work are the the two sharpening plug-ins and Define. The others load normally but all I get is the interface with no image. Has anybody else had this problem? I've uninstalled the package and re-installed it with the same results.
