I installed the Pro version, got both versions 32 and 64 bits on my desktop.
Loading either one takes ages and setting the preferences even more time.
When I load the 64 bits version no sound produced.
When I load the 32 bits version and I am trying to record from my midi keyboard I can hear what I am playing but no info is stored, just a silenced file. Yes I pressed that button to name a file and then it turned red, so I started playing thinking that it now recorded my improvisation... just hopes. No sound......
