you can check what version you have by doing this =
1. righ click on the pg2 icon in the system tray
2. choose About and read the first line there
The latest version is beta 6b, if you doesn't have this one installed, do this =
1) uninstall whatever beta version you have
2) delete the .conf file and the .list files(in the lists folder)
3) install beta 6b.
If you still are using the blocklist.org lists, then the adresses is aren't working because everything is removed there.
