Got a note from Magix support saying that since X6 is 64bit only, the NewBlueFX plug ins will not work. I have about $700 worth of their plug-ins and this is a small problem for me...
Would be nice if they (both Magix and NewblueFX) had thought to advise customers of this...
I am aware that Newblue has 64bit versions for Sony Vegas...so maybe this will be coming for X6...but for the moment,don't uninstall X5 if you have projects that need NewblueFX software...
