No Registration Using Adobe ID & Password!

Question

     I am in an administrator-priviledged user account in (x32) Win XP SP3, on the Internet.  I have my Adobe ID and password in a spreadsheet that is open in one window.  I open the newly purchased, installed, and activated Adobe Acrobat XI Pro in another window and the sub window for Registration of that program is open (either on its own or through the Help menu, it makes no difference) and the boxes for entering my Adobe ID and my Password are showing.  I have opened the webpage "http://www.adobe.com/products/acrobat.html" in another, browser, window, on which I have clicked "Sign In" so it shows the boxes for entering my Adobe ID and my Password in the browser window.
     I copy the Adobe ID from the spreadsheet and paste it in the appropriate box in the Registration window and also in the appropriate box in the "Sign In" window of the browser.  I copy the Adobe Password from the spreadsheet and paste it in the appropriate box in the Registration window and also in the appropriate box in the "Sign In" window.  Identical entries in both windows.
     I click on the "Sign In" button in the "Sign In" browser window and it returns me to the previous,  http://www.adobe.com/products/acrobat.html webpage, but that now says "Welcome .........." and gives my name.
     I click on the "Sign In" button in the Acrobat-XI-Pro Registration window and up comes the message, "The Adobe ID and password do not match. Please try again."
     My system (x32) uses WinXp SP3.  The Acrobat XI Pro was an upgrade from 9 with the uninstal of 9 done as part of the XI install process in what appears to be the normal way.
     Does anyone have any thoughts?  Is this behavior a sign that I will face other problems with Acrobat XI Pro down the road?

Poo jain or other person:
    The exact problem of Oct. 2013 has reoccurred!
    In 2013 I apparently solved the problem - apparently entirely by accident later that evening (because I had no need to return to this thread) - but I made no notes of how it was done.  I used Acrobat XI Pro for 14 months, extensively,  with no problems.
    Now (10 - 21 Dec 2014) I have the exact same problem as in Oct. 2013.  (I had to uninstall Acrobat XI Pro as installing a recommended Adobe update for it caused a constant stream of error windows to pop up.)  No matter what version of Acrobat XI Pro I now install (11.0.0, 11.0.07 or 11.0.08) I get the problem just as stated above.  (As I got a stream of error windows when originally upgrading to 11.0.09 and then when upgrading to 11.0.10 [but it was a different stream of error windows, as I recall], I do not want to install them.)
    It appears I must make a new post to upload the files requested.  The last install of Acrobat (done today, 21 Dec 2014) was version 11.0.07.
    Sharing a file:  I found a link involving sharing a file under Community Guidelines, but that link led to instructions that said I could not attach a file to a post.  It said I could share a file by using Acrobat.com, but the link given there led to an Error Page.  I will keep searching for a way to share the files needed and when I find it I will report back here.  I do notice that my most recent install (of version 11.0.07 done today - 21 Dec) is not reflected in amt3.log and the other two files date from Oct 2, 1213, apparently my initial installation.
    This is looking like a very dead end that I have spent many days on.  It looks like I must abandon using any Adobe software to manipulate PDF files and PDF-file content and go with software by other manufacturers.
