Add On...this is not Adobe. Rather user to user.
Thank you so much for your common sense reply. I contacted Adobe via their online chat help facility. One of their tech guys resolved the issue by re-setting the Hosts file. Now I have seen this in the forums and it basically involves making a back-up copy of the Hosts file deleting certain entries and applying again.. Thankfully this worked for me. But I would urge Adobe to look into this matter as there are many novices I am sure will be extremely frustrated at what should be a straight forward approach when validating their software. Most people would know there internet was working ok and most people would be able to disable anti-virus software etc, but to continue getting a failure to validate a serial number online would in my opinion beggar belief !! for most technically minded folks out there. Most annoying.
When anyone purchases legacy software from Adobe, no one wants this kind of problem. The software is not cheap.
My purchase was Adobe Premiere Elements 13 and it is a great piece of software for video editing. I can however recommend it. It is very good for both novice and professionals
Thanks for the update with the wonderful news that Adobe resolved your Premiere Elements 13/13.1 serial number issue focusing on the hosts file. Great job by you and Adobe on this.
Your follow up was particularly important for those with Sign In, Activation, Invalid Serial Number, and the like problems. So many thanks for that.
Although your problem is resolved, the comments regarding the hosts file and Premiere Elements 12 Sign In may be of interest
Best wishes moving forward in your Premiere Elements projects.
