Hi there Matt Finley,

In fact I am on Win 7.

Yes...I've installed the updates 379, 380 (twice at least LoL).
I never had this kind of problem...I bought all the versions since 2011...never had any problems.

The software works fine ( all the functions ok ) but only the Big Piano Keyboard does not.

I have no idea...no more!

About the folders: just the Drums and Real Tracks (I am using an external HD).

When I click the Big Piano icon it does not respond. As I said...everything else looks fine.

Hope you can help me!
Thanks
