Well, there were two special characters in my initial password created by the switched keyboard and there are two others in the new one created after I'd managed to switch it back to what it should be and they were both accepted. The search took me to this page http://www.unclebob.mangle.ca/delphiaccountfaq.htm , which then directed me in the answer to the first question to this one: http://forums.delphiforums.com/n/mydelphi/myaccount.asp?webtag=mainconf.

Interesting. Looks to be an older page some search engine has stowed in memory.

You do get switched over to https for the login.

Well, I'm glad I found it, because it was the only one that was working!
