The problem is on my desktop unit, HP Pavilion HPE H8-1214 running 16GB RAM on Windows 10 64bit. I have the same program (Vegas Pro 16) on my HP Envy Laptop with 16GB RAM using Windows 10 64bit running with no problems.
I have uninstalled the program,downloaded the install file again, and reinstalled... same issue. I downloaded and installed a copy of Vegas Pro 8; it works properly.
I have made sure the program has been reset to defaults. No change. Suggestions? Help...
