Hi everyone !!
I had the same issue yesterday !
I was working with VEP 5 5ViennaEnsemblePro-WIN-5.4.14074)
When I started VEP it suggested me to upgrade to the next version (ViennaEnsemblePro-WIN-5.4.15566)
I upgraded but In my metaframe I had the same issue Kontakt samples were'nt able to load
So I upgraded to VEP6 (ViennaEnsemblePro-WIN-6.0.15567) (I had bought it a few month earlier but I had not upgraded yet ) and I had the same issue : Kontakt samples weren't loading !!!
And today ! It works
What I've done is : When I saw that my metaframe didn't load Kontakt samples I didn't save my metaframe or what is now called "Server Project" because as it didn't work I didn't want to save.
This morning I opened one of my "Server Project" (Kontakt Samples weren't loading) I saved it (even though I saw it wasn't working the way I wanted) then I clicked on exit. I restarted VEP 6, everything works fine Kontakt Samples still don't load but when I click on Reload all Samples now it works !!
So you have to reload your samples and resave your Server Project once it's done !!!
Hope it might help !!! Let us know
I feel like having a whisky to celebrate but here it's 10a.m so a bit early !! I'll drink later Hope it solves your issue too !
All the best
Jo
