To say I'm fed up is an understatement - especially after over 30 days! 😡
A fresh install of Windows 10 Professional with latest updates on my laptop as Administrator works fine - with literally no other apps installed. Once I log into my user account with admin rights VP15 crashes. This is pretty much the last straw for me. I will not recommend the program to anyone and here I was about to fork over $$$ to upgrade. Glad I didn't. Unless MAGIX can fix this, I won't be working in Vegas any longer as the features in VP15 were what I've been patiently waiting for having bypassed VP14.
Looks like I'm back to what actually works - Adobe CS6 Suite.
