This *is* actually a problem with Ping Plotter.<br><br>What happens is that Ping Plotter *first* tries to read/write the key to/from HKEY_LOCAL_MACHINE. If this fails, then it writes it to HKEY_CURRENT_USER.<br><br>I think your user probably doesn't have rights to create a key in HKEY_LOCAL_MACHINE. There's actually a bug here that doesn't write the key out correctly to the HKEY_CURRENT_MACHINE key - and instead writes a "unregistered" key to the registry. This *appears* to happen when there isn't a key in HKEY_CURRENT_MACHINE only.<br><br>I think you'll probably be able to work around this now by re-entering your registration data into Ping Plotter. Another possibility is to delete the "Nessoft" key from your HKEY_CURRENT_USER entry when logged in as your own user. When Ping Plotter doesn't find an entry here, it will look to the HKEY_LOCAL_MACHINE entry that was written out correctly when you were logged in as administrator.<br><br>To summarize, here's what to try:<br><br>1) Just re-enter the key when logged in as your own (non admin) user and see if it goes better this time (it should).<br>2) Delete the HKEY_CURRENT_USER\Software\Nessoft\PingPlotter key from your registry.<br><br>This should solve your problem.<br><br><br><br>
