korg microkontrol with presonus studio one

[goldspanner]

running my microkontrol with presonus studio one.
I was originally running studio one v1.6 32bit on windows 7 64 bit, I have the 64 bit drivers and it showed up in presonus as a usable keyboard.
I've just updated to studio one v2 and now it only shows up in the 64 bit install. I would just run 64bit studio one, but Jbridge has a habit of crashing alot.
I've checked with other standalone apps i.e. massive and the keyboard work fine. I also tried in reaper and it doesn't show up there either.

Any ideas?

Cheers
Alex
