Welcome to the forum.
The few references to that error that I could find, seem to relate it to the QuickTime .PRM file.
Do you have the latest version of Apple's QT Player installed? If not, I would download and install that, then test.
I do have it installed i forgot to mention that i updated it after these errors, is there anything else i can try?
Since your duplicate thread has been closed and all replies directed to this one, I wanted to make sure that you did not miss my message going between threads.
The following is a copy/paste of what I wrote in your now closed thread:
Please avoid duplicate posts since they tend to confuse the person writing them as well as the people trying to respond to the question.
I have seen the error that you present appear often, but I have not seen an agreed on the resolution, if a resolution at all.
What I would do first is to update your Premiere Elements 12 to 12.1. See the opened project's Help Menu/Updates. If the problem persists after the update to 12.1, then let us look at the Scratch Disk set up and situation.
When you go to Expert workspace, Edit Menu/Preferences/Scratch Disks, where are all the categories directed to on the computer hard drive and how much free space is at the location(s)?
Did you install Premiere Elements 12 to its default location or other. If other, where?
There are a lot of Troubleshooting avenues to go down (some old, some new, some questionable), but let us start with the above and then decide what next.
But before all that, please respond to the questions already asked you by SG.
