Problem with old Adobe ID

I've been a Photoshop user for a very long time (~1994).  When Adobe created online accounts for customers, I created a single-word login name, which was normal at the time.  Sometime later, Adobe switched to using your email address as an Adobe ID, but my old ID was "grandfathered" and I continued to use it.  However, a number of Adobe products and systems now assume that all Adobe IDs are email addresses, and various things no longer work for me.

As of yesterday:

- I can log in to My Adobe successfully using my single-world login name and password.

- I *cannot* log in using my email address and the same password; the login processor says that the ID and password do not match.

- If I use the "I forgot my Adobe ID" link, Adobe will send me an email message, to my normal email address, listing the single-word login name (not an email address) as my true Adobe ID.

- If I log in to My Adobe and go to the "My Information" page, the "Adobe ID" box lists my email address.

- I have tried to change the "official" version of my Adobe ID to be the email address instead of the single-word name, but attempts to change it have failed (possibly because that box already has the correct email address in it, and I'm trying to change it to the value that is already shown)

So, it appears that I'm stuck with the single-word version of my Adobe ID, and am unable to change Adobe's database to accept my email address instead to access my Adobe records.  But why do I care, since I can still log in to the My Adobe login page using the old version?  Because a lot of Adobe software now assumes that Adobe IDs must be email addresses, and simply do not work with the old single-word form of Adobe IDs.  For example:

- I tried to download trail versions of Photoshop Elements 11 and Premiere Elements 11.  The downloader app supplied by Adobe (for Windows) asks for an Adobe ID, and rejects anything that does not contain an "@" sign.  So it won't take my single-word Adobe ID, and my email-addresss Adobe ID gets the "ID and password do not match" error.

- I managed to download the trial versions by creating a new throwaway Adobe ID, and installed them successfully.

- But when I run the trial versions, they want my Adobe ID and password.  The trial versions will not accept the single-word Adobe ID, and the email version fails.

- The trial versions allow me to skip the identification page and run them anyway, for now.  But I expect I will probably buy the programs, and worry that I won't be able to register the programs if the same brain-dead logic is present in the registration code

Essentially, Adobe's software is broken in its handling of what was once a legitimate Adobe ID, and there doesn't seem to be any way that I can change my Adobe ID.  Nor can I find any email support address for Adobe ID account issues.

Can anyone suggest a way to avoid the problem, or get Adobe to fix their Adobe ID database?
