Spark 2 (part of V-Collection 4) not running under Yosemite

[flonky]

Hello,
I just bought a new Mac Pro and migrated my stuff from my old iMac.
All Arturia instruments worked fine after updating them except Spark 2.
I reinstalled it using the V-Collection 4 Welcome App but it quits as soon as I launch either standalone version or it crashes Logic when loading the AU-plugin.
Is there anything I can try to make it run?
Thanks,
Florian

The only fix I know of (because i've done it once when Spark started crashing at each open) is to delete the Spark .prefs files.  Search the Spark forums here about it before deleting, but the prefs files are located in /Library/Arturia/Spark

working good here on yosemite, not files to delete to make it work on my side
