•What version of Premiere Elements? Include the minor version number (e.g., Premiere Elements 12 with the 12.0.1 update).
•What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac"
•Has this ever worked before? If so, do you recall any changes you made to Premiere Elements, such as adding Plug-ins, brushes, etc.? Did you make any changes to your system, such as updating hardware, printers or drivers; or installing/uninstalling any programs?
•Are you using an account with Administrator Privileges?

•If you are getting error message(s), what is the full text of the error message(s)?
•What were you doing when the problem occurred?
•What other software are you running?
•Tell us about your computer hardware. How much RAM is installed? How much free space is on your system (C:) drive?
And some other questions...
•What are you editing, and does your video have a red line over it BEFORE you do any work?
•Which version of Quicktime do you have installed?
What is your exact brand/model graphics adapter (ATI or nVidia or ???)
What is your exact graphics adapter driver version?
Have you gone to the vendor web site to check for a newer driver?
For Windows, do NOT rely on Windows Update to have current driver information
-you need to go direct to the vendor web site and check updates for yourself

nVidia Driver Rollback PreElements-10 http://forums.adobe.com/thread/1317675
Does your computer use a NVIDIA GeForce video card/graphics card? If so, you are mostly likely to have run
into the epidemic of display errors specific to the Premiere Elements 10 NVIDIA GeForce user.
The answer is to roll back the driver to an earlier version, typically around May 2013. The information on this
is in the Annoucement at the top of this forum. For your convenience, the following is a copy/paste of it
Premiere Elements 10 NVIDIA Video Card Driver Roll Back
If you are a Premiere Elements 10 user whose Windows computer uses a NVIDIA GeForce video card and you
are experiencing Premiere Elements 10 display and/or unexplained program behavior, then your first line of
troubleshooting needs to be rolling back the video card driver version instead of assuring that it is up to date.
Since October 2013 to the present, there have been a growing number of reports about display and unexplained
workflow glitches specific to the Premiere Elements 10 user whose Windows computer has a NVIDIA GeForce
video card. If this applies to you, then the “user to user” remedy is to roll back the NVIDIA GeForce video card
driver as far as is necessary to get rid of the problems. The typical driver roll back has gone back as far as
March – July 2013 in order to get a working Premiere Elements 10. Neither NVIDIA nor Adobe has taken
any corrective action in this regard to date, and none is expected moving forward.
Since October 2013, the following thread has tried to keep up with the Premiere Elements 10 NVIDIA reports
Older NVIDIA GeForce drivers can be found
A February 2014 overview of the situation as well as how to use the older NVIDIA GeForce drivers for the
driver roll back can be found
Recently one user has suggested deletion of the BadDrivers.txt file in these instances instead of the driver version roll back, but more data on that is needed. The above works. BadDrivers.txt file deletion details will be supplied if indicated.
To be explored...the properties of your source media to assure that you are not dealing with formats problematic to Premiere Elements, such as Xvid.avi, AVCHD.avi, or others. A quick way to get at that is to know the brand/model/settings of the camera that recorded that video.
We will be watching for further details and your follow up.
