Adobe Acrobat upgrade has destroyed the signature and in the IE a certified web site displaying

Question

I have encountered a very strange, but exactly the same phenomenon on my desktop PC and laptop. (W XP Professional, SP3, IE8)
The Adobe Acrobat (v.9.4) has been upgraded with the online refreshment process on both PC and now I can not use a web site at all
on both PC.
In the IE when I start the  URL the popup windows with Certificate selection appears normally, but when I accept
it after that I have the below screen:
Translation: 
The IE can not display the web page.....
Possible steps:  diagnose the connection problems
Additionally my own created signature in both Acrobat has been damaged too. When I
want to use the signature I get an  error message:
Translation:
The Windows encryptioning service has indicated an error:
The object does exist.
Error code:  2148073487
I tried to uninstall - reinstall the Acrobat as well as the signature, but did not fix the problem.
Does someone have any idea what could be the problem and how I could restore the functionalities?
