Last week I was trying to access the quartus web site to download and there was no way to add an account. I figured it was due to the pending cut over to the intel web site. Now this week it looks like you could possibly login with your intel account but that seems screwed now as I cannot even login to Intel's main web site any longer. Also getting no response from password reset requests.
I also had a similar issue on Xilinx web site last week. I had an account there for almost 10 years but account was not accessible with passwords I know were correct. I sent many reset password or recover account requests via the web site and got total silence in response.
When I contacted them via website feed back, finally I was told my account was removed due to inactivity. No warning, so frustrating - this is what I call terrible customer service.
Do they care - I seriously doubt it :(
