The update won’t download or the file is corrupted. Why?

Some download managers may take over this download process and interfere with normal operations. When this happens, temporarily turn off your download manager and try again. Another frequent problem is that a firewall is blocking access to the news server on the Internet. If you are using Windows Firewall and NoteTab cannot reach the update server, make sure that you uncheck the option labeled Block all incoming connections(Windows 7 and Vista) or Don’t allow exceptions (Windows XP); you will find the option in the Windows Firewall settings window which opens from the Control Panel. If this setting is enabled, you are not notified when Windows Firewall blocks programs, and programs on the Exceptions list are ignored.
