With Premiere Elements 10 and earlier, you no longer Sign In. That Sign In was disabled by Adobe several years ago when Adobe discontinued photoshop.com.
Open the program, and, on the Welcome Screen, hit New Project if you want to start a new project, set up the new project dialog, and click OK in the new project dialog
to gain access to the workspaces.
Have you done that and still cannot start a new project?
If so, what video card/graphics card is you computer using - NVIDIA GeForce or other.
Please review and consider and then we can decide what needs to be done.
As I mentioned, I've used premiere elements numerous times so it works with my video card (NVIDIA). When I try to open a new project from the welcome screen it just doesn't open. I can open organizer but not the video editor? I've tried re-installing the software with no help.
There is a known issue with Premiere Elements 10 and computer's that use a NVIDIA GeForce video card/graphics card.
Please go to Device Manager/Display Adapter/name of your NVIDIA card/Driver Tab of its properties. What is the driver version
and date. Anything older than May 2013 has created Premiere Elements 10 problems. It could be that your driver version was
automatically updated. Having the latest driver version is definitely not wanted in this situation. That is why I need to have you rule this
factor in or out at the onset of any troubleshooting.
If we can, then we need to look at program activation issues.
