I just recently purchased VE Pro 6, and I'm having the issue of Kontakt going through the "loading sample data cache...please wait" every time I open a .vesp project. What's odd is that I didn't have this issue while I was on the 30 day demo, but right after I activated my purchased licenses I started having this issue. I am on Windows 10 x64. The project doesn't get stuck, it just goes through that step with EVERY instance of Kontakt that I have, EVERY single time I open the project. So thus it takes probably around 10 minutes for it to even open. 

Any help would be appreciated. I have Kontak and VE Pro all added as exceptions to Windows Defender as well. On Kontakt 5.6.1.

Hi Paul,

Nothing seems to have changed. Everything is as it was before I updated the license. I tried reinstalling VEP, and the first time it opened it did not attempt to do the sample data caching with kontakt. But then, unfortunately, one of the synthesizers I had loaded into the project caused it to crash, and after that every time it would do the caching. After testing it repeatedly, it seems that one of my synths is causing VEP to crash every single time. It seems to be either Serum, Zebra, Massive or Element. Are you aware of any compatability issues with any of these? Quite annoying considering once I loaded it in, I now can no longer  open the project, as it just crashes when it gets to loading in the synths.

EDIT: Can now confirm it is Waves Element. I removed the waveshell vst from the plugins folder that was included in VEP's preferences and the project was loaded properly. 

Is there any news regarding this issue? I still have the same problem since several months. From time to time VEP6 hangs with this message. Force quit and having another start is the only solution. After two or three tries the project loads with no problems...

I get this too, about 1 time in 2-3, usually first launch

macOS 10.12.3

Best

We have this too, about other day. Only with VEP loaded K5 files. Works fine inside host daw.
