I tried to add my LR 5.7 license I bought a while ago to my adobe account.
When I tried it on the website, i put in the license code and clicked on "save" - but it didn't happen anything. I tried it with the up-to-date versions of Chrome and Edge. I also tried it on the mobile phone without success.
In Lightroom 5.7 it should be also possible to register a product, but when i filled out everything i just could click on "finish" instead of "next".
Does anybody know what's the problem?
