You're welcome. Unfortunately I do not know what caused this, or if it will work better in future.
You have now 11.0.0 installed; can you try to open Reader, then Help | Check for Updates. Then we will know if updates work normally.
Alternatively you can download the 11.0.2 update from https://www.adobe.com/support/downloads/product.jsp?product=10&platfor m=Windows
