Adobe Download Assistant Will Not Recognize My Adobe ID

Question

I've been an Adobe customer / forum user since before ID's were tied to email addresses.  My product registrations going back to 1996 through CS 5.5 apps are recorded under that ID.  Since I have to change my email address every couple years to escape spammers, I do not want to change my Adobe ID (and go through the hassle of re-recording the record of registered apps) to a "fluid" ID like an email address.
Automatic registration and now Adobe Download Assistant will not accept an Adobe ID that is not an email address, yet I can still use it to 'manually' register new / upgrade product purchases.  The problems this poses are two-fold:
Since I can only manually register new / upgrade products, I cannot obtain any "registration bonus" downloads.
I cannot download trial versions of apps I want to check out.
Adobe needs to get its act together and tell its gen-X / Millenials / Kid Web and software development staff that not all Adobe IDs are email addresses, but might also be a unique user ID string.
Further, due to an individual's email address volatitility (virtually everyone in my email address book had their email address change every 2- 3 years due to ISP demise, merger, personal relocation, job change etc.), Adobe should return to - or at least give precedence to - the model of UID / PW authentication instead of email address / PW authentication.  This would lower Adobe maintenance effort / cost for user accounts as one could simply sign in with UID + PW and change email address for the account as necessary.  As it is now, Adobe CANNOT deal with a user whose email address changes. 
When Adobe changed from UID precedence to email precedence, I could not register Acrobat Pro (2007) during registration so I used my email address at that time to register the product.  When that email address ceased to exist, I tried to get Adobe to transfer that registration to my old [non-email address] Adobe ID, and, over several months of email exchanges, they ended up admitting they could not do it.  I could not make the change as the SN was already marked as used in there system so simply re-registering it to my existing account wouldn't work either.
This has been an ongoing issue with "legacy" users since 2006 at least, and NEEDS TO BE RESOLVED ASAP!!!!

There you go MISSING THE POINT AGAIN!! My Registered products WILL NOT FOLLOW MY UID IF I CHANGE IT, NEVER DID SINCE 2007.  Saying the will is false information which I alerted Adobe to back in 2007 and is a problem y'all never fixed.    
Just a little over a week ago, I got I got LightRoom 4 ug from a LR 3 I had purchased in March.  Signing on with my legacy UID (non-email) allowed me ADD those registrations to my account, as I had cor CS 5.5, 4, 3, etc. etc.  Now, isn't it odd that the very day after I posted here, when I sign in to my account it shows NO REGISTERED PRODUCTS!!!  If I look at my order history, it has orders from Adobe store from last weeks CS6 MC purchase back to 2007 when I started buying from Adobe directly after the local brick and mortar resellers disappeared. 
So I try to register CS6 MC, it tells me the SN is already in use.  I try open a PDF document and it tells me I have to first register and agree to the Acrobat Pro X license before I open a doc - and it was an UPGRADE FROM CS 5.5 MC.  I try to run CS 5.5 apps and they tell me I have to purchase a license since the trial period is over - HUH!  Until I posted here it was working FINE.  I go back to my acccount (non-email UID sign in) and check my profile - Lo and behold SOMEONE (not me) has changed the UID to an email address instead of the non-email UID I sign in with AND DELETED ALL MY PRODUCT REGISTRATIONS!
Naturally, your software does not let me put it back to the same UID I use to sign on with so THE LINK TO ALL MY REGISTERED PRODUCTS IS GONE, I CANNOT REGISTER NEW ONES (which was no problem just a day or two before posting here) WHICH PROVES WHAT I WAS TOLD IN 2007 - WHEN YOU CHANGE UID'S YOUR LEGACY REGISTRATIONS WILL BE LOST!!!
So, in summary you (Adobe at least, and I suspect you personally) went in and messed with my legacy account, deleting all my registrations, as I was told in 2007 would happen and advised to keep the old UID if I did not want to blow away those registrations, when I explicity did NOT want to make such changes.  And, should I need an SN for some upgrade offer or to install an update for an older product that I did not transition to the new facility, I have to HOPE that I had I can find the original purchase invoice and that there is a copy of the SN / Reg card attached to it.
THANKS A PANT LOAD!!
