Hi, I have Premiere Elements 12.1 on windows 8 and now and again Premiere will no longer play the time line either from pressing the play icon or using the keyboard,,,or even on the on screen keyboard. It requires a reboot of the machine to get going again.frame by frame works but fast forward doesn't
I triws to remap it to a different key but that didn't work. Sometimes the image in the preview windows above the timeline will go black when I press the play key. restarting the application doesn't fix it either.
Any ideas as it quite frustrating.
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
ATI Driver Autodetect http://support.amd.com/en-us/download/auto-detect-tool
nVidia Driver Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us
Also, what are you editing?

And finally, are you sure your project matches your video... is there a red line over your timeline before you do any work?
