FAQ - When I try to start News Rover it says "Another copy of News Rover is already running".

The specific cause of this error message is that News Rover is unable to open a file named ng.dat in the directory where it is installed. Normally this is c:\Program files\Newsrover\ng.dat

The first thing to check is whether this file or the enclosing directory has gotten set to read-only access. Use Windows Explorer and browse the News Rover installation directory. Make sure the directory is set to enable write access, and check the ng.dat file to make sure it is also set for write access. Here's how to do it:


  1. Use Windows Explorer to browse the directory where News Rover is installed. Normally this is C:\Program files\NewsRover
  2. When you find the entry for the News Rover folder in Windows Explorer, right click on the icon for the folder and select Properties from the popup menu.
  3. Click the "Read-only" checkbox until the check is gone and the box is empty. Then click the Apply button at the bottom of the screen.
  4. If prompted, select the option to aply the attribute to the current folder and all sub-folders.
  5. Once it finishes setting attributes, click OK to close the attribute window, then close Windows Explorer.

If you don't find a problem with the files, the next thing to try is rebooting Windows to see if that clears some file lock problem.

If rebooting doesn't solve the problem, press Ctrl-Alt-Delete to bring up the Windows Task Manager. Look at the list of processes and see if you see NewsRover.exe running. If you see NewsRover.exe in the process list but its screen isn't visible, let us know, and we'll give you some other things to check.
