>Do you have Premiere Elements 10 along with the NVIDIA GeForce 780 on the Windows 7 64 bit computer?
Yes.
I did a small video yesterday, cut it with GoPro Studio and encoded to FLV with Premiere Elements 10 (preview not working, so cutting no possible). Then I started searching for video editing SW offers, and happened to find this forum. Removed BadDrivers.txt and started PE10 yet again and the preview worked! So no need to buy other software, great!
Previously I have used old NVidia drivers, as PE10 preview works with them. But some games don't work well with the old drivers, so swapping between old and new driver is time consuming.
