Upgraded from the trial version, now Premiere Elements won't work

>Intel HD 630 Graphics (6Gigs) and Radeon RX Vega M GL Graphics (4 Gigs)

I have an Intel i9 which has the same built in graphis process

I also have MSI GeForce GTX 1650 128 Bit Graphics 4Gig

In MY system (ASUS-Prime-Z490-P motherboard) the Intel 630 graphics is automatically turned OFF when I put in the MSI card... so there is no confusion

If you have both graphic processes active you MAY be having a problem of video confusion

You need to provide details for anyone to help
Mac or Windows and exact version of the operating system
CPU brand and model and clock speed
Amount of computer memory (RAM)
Video adapter brand and model and driver version and amount of video ram

Do not count on Windows to be fully up to date when it comes to device drivers
Go to the vendor site to be sure you have an updated driver for your graphic adapter
nVidia Driver Downloads https://www.nvidia.com/Download/index.aspx?lang=en-us
-for Premiere Pro (and MAYBE Premiere Elements) use the STUDIO driver, not the GAMING driver
If you have a laptop you MAY also need to check for a laptop specific nVidia driver
AMD/ATI Driver https://www.amd.com/en/support
Intel https://downloadcenter.intel.com/product/211969/Intel-HD-Graphics-Family
There are also intermittent reports that the newest driver is not always the best driver due to driver bugs or compatibility issues, so you MAY need to try an earlier driver version
