From the Premiere Elements Information FAQ http://forums.adobe.com/thread/1042180
•You MUST use an account with Administrator Privileges to run Premiere Elements
•(Doing Run as Administrator http://forums.adobe.com/thread/969395 [says Encore and also for "All" versions of Premiere] will sometimes fix "odd" errors)
•What version of Premiere Elements? Include the minor version number (e.g., Premiere Elements 12 with the 12.1 update)
•What operating system? This should include specific minor version numbers, like "Mac OSX v10.9.4"---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?
•Have you installed any recent program or OS updates? (If not, you should. They fix a lot of problems.)
•What kind(s) of image file(s)? When talking about camera raw files, include the model of camera.
•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?
•How many and what speed are your hard drive(s)... ie 5400rpm or 7200rpm or?
And some other questions...
•What are you editing, and does your video have an orange 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 Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us
•ATI Driver Autodetect http://support.amd.com/en-us/download/auto-detect-tool
-and a fix for at least "some" ATI crashes https://forums.adobe.com/thread/1553342
The why will need details of your situation.
On what computer operating system is your Premiere Elements 11 running? What is a description of your computer resources?
Then there are a series of questions that need answers
1. Does the problem exist with and without the antivirus and firewall(s) disabled?
2. Do you have the latest version of QuickTime installed on your computer with Premiere Elements 11?
3. Are you running the programs as administrator?
4. What are the properties of the files that you have on the Timeline? Brand/model/settings of camera that recorded the video would give us valuable information for the troubleshooting. If photos, how many and what pixel dimensions - way over 1920 x 1080?
5. What is the project preset which should match the properties of the source?
6. What is the size of the project when the project shutdown? Are you running the project with its AutoSave feature enabled? If so, can you open one of the AutoSaves to continue in the project?
7. Does this problem exist only for this one project? Anything specific that are you doing in the project when it shuts down?
Please review and consider, and supply details. Then we will decide what next based on the details in your reply.
Do not hesitate to ask questions or ask for clarification on anything above.
I did not see John's post 1 until after I had posted mine (post 2).
In spite of any overlapping, I would still need answers to all the questions that I have customized and asked so that I can give you a customized troubleshooting plan.
