Acrobat XI installed and runs but cannot update or register?

Question

Acrobat XI installed and runs but cannot update or register? typical fixes don't work or apply. Seems to be a very peculiar situation. Any thoughts?

Anubha,
If I open acrobat 11.0 and click on Help before I open a file, there is no choice of Product Registration.
If I open a file, and click on Help, there is a choice for Product Registration, but it is transparent and cannot be selected.
If I close that file but keep Acrobat open, a large dialogue box will pop-up asking me to register, and when I proceed, and after about 2-3 minutes, I receive another pop-up saying to check my connection and retry. I can
   retry over and stay in this loop. But when I close the registration pop-up and go back to Acrobat, the Product Registration selection under Help is no longer transparent, and I can select it. But when I do the Registration dialogue box returns, and when I proceed, I get the same no connection-retry pop-up and the loop continues.
In fact, I have done just now, what I describe in the sentence above, in the time between what I typed above and what I am typing now in my open browser window.
If I click on Help and select Adobe Help, a new tab opens in my browser showing Acrobat's Help page, as it did, just before I typed this sentence.
If I click on Help and select Online Support, and then select Knowledge Base, it takes me to a new tab in my browser which is the same web page as I get when I press F1.
I have selected 'Repair Acrobat Installation' from the Help menu twice and gone through the process with no change in outcome.
If I click on Help and select Check for Updates, it seems to be updating, then stops the process, and I get the Registration pop-up, and the same thing.
This seems entirely bizarre.
What do you think?
