I am getting a bit concerned about what is happening in your situation. Yesterday you posted your question in at least two different forums, one of them being here in the Premiere Elements Forum.
Wherever you posted, the reply was to contact Adobe via its Adobe Chat. It is the only one who can sort out this matter for you.
In the thread cited above I offered to help you with the difficulties that you were having visualizing the Adobe Chat in its web page. I was waiting for your follow up on that in the above thread. Instead, I find your same question in a new Adobe Premiere Elements Forum thread this afternoon with no refer the prior threads or prior recommendations given you.
I will also mention again...when you buy the Photoshop Elements and Premiere Elements bundled in one packaging and with installation files for each on the same installation disc, each program has its own serial number. The Photoshop Elements serial number does not work for Premiere Elements and vice versa. The serial numbers are on labels on a box which houses the installation disc envelope(s). So, if you purchased both programs and found the Photoshop Elements serial number, then the Premiere Elements serial number should be in a label right underneath the label with the serial number for Photoshop Elements. I recall writing this in your yesterday's thread on this matter.
The moderator will no doubt be along shortly to close or delete this thread. So, just in case, please bookmark your yesterday's thread cited above so that we can continue this communication which is trying to help you.
