I'm not sure how I can assist if we don't break down the specifics on a real simple level here.
 
When you say "register" are you referring to filling out the form at www.cakewalk.com/register ? It sounds like you tried doing this, but it shouldn't be necessary. When a product is registered to you, you never have to do it again. You do have to authorize your products with the given registration code however. Essentially you just need to match the Serial Number/Registration Code combination as shown in your My-Account Products list. I can see you have a few instances of Dimension Pro. I'd just try matching up the Registration Code with the displayed serial number when authorizing Dimension Pro. Again, make sure you're running SONAR as an administrator or it will reject the code. More information can be found here: http://www.cakewalk.com/S...using-the-correct-code
 
Cakewalk Command Center and our website both use the same login credentials, however logging in/out of one does not log you in/out of the other. They are separate applications. I can 100% assure you that your YouDontHasToCallMeJohnson does not have any product ownership. What I guess I'm confused about is where you are seeing your other account information. Can you help to clarify? Is it in Command Center?
 
 

It is possible IE had some persistence. But I had closed it repeatedly. During this process.
 
I had logged out of Johnson, into the other account, logged out, in with Johnson and the products were displayed from the account page.
 
At this moment Johnson has no products listed. I am sure I was logged into that user.
 
-------------------
 
I just uninstalled DP and installed again using the serial number as listed in the CCC. I start DP, enter the listed reg code, and am informed code is incorrect.
 
I click the register button, it opens this page:
https://www.cakewalk.com/...=CWDM150&sn= [SERIAL NUMBER REMOVED]
 
The serial number in the box is the same as listed in the CCC.
 
I click register and this page is displayed:
https://www.cakewalk.com/Register
"""This serial number has already been registered but it appears to be registered to another customer. """
 
Johnson is listed as being logged in. So this indicates to me, the browser login to the website supercedes DP's attempt to display correct registration information.
 
----------------------
 
I will now uninstall again. And find the previous update/install and try the codes.
 
And then attempt to install the already downloaded DP .14 file.

Can you clear your browser's cookies? It's very possible that you're hitting the logout option but not being fully logged out. Clearing your cookies should do the trick.

Can we now have multiple identities with Cakewalk and the forum. I thought the single user account thing was supposed to prevent this sort of thing.
