activations

Same problem as    you have  . A lot of difficulties to be able to contact Adobe. It would be much more efficient if Adobe could respond in writing to emails. I sent a first  email with my email address and a second one by replying to the Adobe address that had sent me the serial numbers. Each time, no answer and referral in the maze of searches of a solution. In short, I was finally able to activate Photoshop. The problem: Adobe has released the serial number of Photoshop 2021 (and no Phtoshop 2022 purchased). While searching and by chance, I downloaded the 2021 version after entering in my Adobe account the serial numbers received for Photoshop 2021. I hope I was able to help other Internet users. I read now that the 2022 version has just been released. As I have bought the 2022 version, I suppose that Adobe will send new series n° and that I will be able to use the 2022 version?

Also make sure you are using the serial number, and not the redemption code.  You submit a redemption code to get the serial number. 

Make sure that you have the PSE serial number for PSE and the PreEl serial for PreEl and you didn't swap them.

You need to contact Adobe directly for activation issues. Try again to reach them via phone or chat. Hopefully you will be directed to an agent who can help. . Be assertive, make clear that you do not require assistance with the software, just activation. If necessary, request to be connected to a supervisor.
