Thanx Carl!!!

I know some people where having issues with Play's recent updates and had rolled back to earlier versions - anyone having those issues tried this yet?

I been fortunate not to have any issues...

I haven't tried it yet and I've had a bunch of problems. Of course that's part of why I haven't tried it. I've completely had it with EastWest's BS. I bought Komplete, Kick Hunter's stuff, Olympus Choir, Halion, and a couple other things and just jettisoned Play from my workflow. Been MUCH happier since :D
 
So I may try it some day, since I still own a number of their libraries but I'm not really chomping at the bit :P.

I use PLAY for Hollywood Brass, HStrings inside VEPro5. It seems to working fine so far, didn't have issues with the previous version either.
