Moving this discussion to the Premiere Elements forum.
Tonebone to confirm are you referring to Premiere Elements 12?
Are you trying to open a project created in version 3 in version 12?!
That's a very bad idea. Very few versions of Premiere Elements are backwards compatible.
At best, you'll get a very buggy project (as you're seeing). At worst, your original project will get so badly corrupted that you won't be able to open it in either version.
Particularly in this case, you'll want to finish your project in the Premiere Elements version it was created in, and start your new projects in version 12.
so, you are suggesting to start this project all over again?
Did you try to install Premiere Elements 3.0/3.0.2 on Windows 7 64 bit?
Where is all the media that went into Premiere Elements 3.0/3.0.2?
Yes, you should definitely NOT open your version 3.02 project in version 12. It can only lead to problems and corruption.
In fact, I hope that you kept a copy of your original version 3 project file because you may have corrupted it by even attempting to open it in version 12.
When I installed Element 12- it put all old files into the 12 icon. When I try to open Element 3 in the upgrade
it is looking for a codec. It use to give a serial number in order to be matched with a number given to you by
Adobe once you showed it on line. But it is no longer supported. So, can you help me out in anyway?
There are many reasons why a project.prel from an older version will not open in a later version.
But, let us check to assure that the problem is not in how you are going about doing this. So, please excuse if I go over what you already know and are doing.
Given you have Premiere Elements 12 installed on your Windows 7 64 bit computer.
a. Where is the Premiere Elements 3.0/3.0.2 project at this time and in what format? And, where are all the files that went into that particular project? Ideally one would like to know that you archived the 3 project so that you have a
Trimmed or Copied Folder which contain the project file (project.prel) as well as copies of the media that the project needs.
b. Do you just have a Premiere Elements 3.0/3.0.2 project.prel file by itself saved to a hard drive location on Windows 7 64 bit?
Either way, the first step is to right click that Premiere Elements 3.0/3.0.2 project.prel and select Open With. From the list that appears, select Premiere Elements 12. What happens next will be influenced by whether "a" or "b" exists.
Please review the above. I am not completely clear your details in your post numbered 7. I am hoping that after you review the above we will be closer on what needs to be done. The final answer is likely to be to start the project anew in version 12. But, first we will double check to make sure that we do not have any other choice.
