I recently reinstalled Acrobat 8.1. When I try to check for updates, it says that there's no internet connection. I have checked settings and firewall. No issues. What's wrong?

Question

I recently reinstalled Acrobat 8.1 after a crash.  I wanted to check for updates but encountered the message that no internet connection was found, to check the internet settings or the firewall.  There are no issues with either.  Obviously, I have an internet connection.  How do I resolve this issue?

Hello Coldwater Card,
Please try the following steps and let us know if this fix your issue :
Operating system hosts files map host names to IP addresses. An incorrectly configured hosts file can affect your computer's ability to connect to Adobe's activation servers.
Follow these steps to see if there is a problem with your hosts file and to reset it if necessary.
Click this link.
If you see two Adobe logos, then you have access to the activation servers. Try activating or starting your software.
Still have problems? Go to the next step.
Start an internet browser, such as Firefox or Internet Explorer, and go to:
CS5.5: https://activate.adobe.com/test
CS6 and later: https://lm.licenses.adobe.com/gdf/status.jsp
If you see a test successful message (see screenshots below), then you have access to the activation servers. Try activating or starting your software. 
CS5.5: Test successful
CS6 and later: Test successful
Still have problems? Proceed to Step 3. Reset the hosts file.
Reset the hosts file:
