Yakuza 5 - Not Loading

I’ve been playing through all the Yakuza games and been using Special K and SKIF for all of them, I’ve jsut started playing Yakuza 5 and it refuses to load with Special K loaded.

If I hit Launch on SKIF it’ll start loading the game and the application starts to load, but never opens the game. If I stop the SK service or close SK completely, the game immediately springs to life.

This is the only game I am having issues with.
