What computer operating system is your Premiere Elements 12 running on? And, have you updated 12 to 12.1 Update using an opened project's Help Menu/Update. If not, please do so. Background information for now.
1. Please make sure that you have the gray tabs of the WorkArea bar spanning the complete section of the Timeline that is to be rendered.
2. Make sure you are looking at the orange line above the Timeline content rather than the orange line that runs through the clips (rubberbands)
Depending on your review of the above and your results, you may want to post a screenshot of your Timeline
showing the opened track contents.
Also, where are the Scratch Disks directed and how much free hard drive space is at that location(s)..
Please see Edit Menu/Preferences/Scratch Disks.

can use the following shortcuts....
Move the Timeline Indicator to the beginning of the segment that you want to render. Then as you hold down the Alt key of the computer
main keyboard, press the left bracket key [
Then move the Timeline Indicator to the end of the segment that you want to render, and, as you hold down the Alt key, press the right
