Having the same question with the people who asked the same question before, although it was said to have been resolved before, but I still encountered the same problem.
I've tried both re-registering with a different email address and changing password, but didn't work.
Hi againThanks for trying again to obtain an evaluation license for Arm DS, but sorry that it still doesn't work for you. Unfortunately, I don't know what might be causing this issue for you.Please log-in to the Support > Arm Support Services from the links at the top of this page (developer.arm.com/user-login), and create a Case for the Support team to investigate further.Stephen
