Hey, so to address your first concern there are 2 paths, the first is if you haven’t re-registered your account on the elektron.se site after last year’s website overhaul that they did, then you’ll need to do that using your same email and that may take care of the error.
There’s a thread with info about that and I’ll look for it in a minute.
If you’ve already re-registered then the error might be something else but I’d try clearing cookies and browser info to start with and make sure the email that you’re using aligns with your registration, and if the usercare@elektron.se is still listed on the website, then it’s still a valid email.
As far as response times, I don’t know what to tell you. There have been various reports of long response times and then some people say it’s not an issue but assuming that it’s Sunday for most of us, then the amount of time in “business days” is negotiable so maybe give them another day or 2 before we decide the email you sent didn’t reach them.
I’ll find you a link to the topic where people were talking about issues logging into the site.
