The problem is likely your antivirus, which might mistakenly blocking the program *BECAUSE* it has been updated.
If you absolutely sure your antivirus is properly configured, and your firewall is not blocking the download, the thread named "Addon Manager not showing up in P3Dv4 **SOLVED**" thread lists all the known solutions for missing menu entries from the "Addons" menu:

If that doesn't work, you should do the following to enable Logging:
- open the Notepad and type the following on a new blank file:
logFile=couatl.log
(please note logFile is written beginning with a lower case L and a capital F )
- Save the file as couatl.ini in the %APPDATA%\Virtuali folder
- Delete %PROGRAMDATA%\Virtuali again
- Run the sim, then exit after it disappear after the cache recreation.
- Check your %APPDATA%\Virtuali folder and if there's a Couatl.LOG file there, post its content
- DO NOT copy the file in a message, but use the "Attach" function of the forum to ZIP the log file and Attach it to a post.
