I have a script using the invokeLater() function that eventually opens a screen.

In my old script I had the line:

```
system.nav.openWindow('Main Navigation/_Navigation')

```

In my new script I have the line:

```
system.nav.openWindow('Main/_Navigation')

```

Now when I save to the gateway and run the new script I get the following error:

```
Traceback (most recent call last):
    File "<event:propertyChange>", line 31, in evaluateRFID
ValueError: Window Main/_Navigation does not exist.

```

Does anyone know how I can reset the gateway to read my new script and discard the old script? I know it has something to do with the invokeLater() because I delete everything but the following:

```
system.gui.messageBox('hello')

```

and everything is fine. I put the new script back in and the error comes back.  
Thanks for any help.

After carefully checking my syntax I found a user-error. The path name was not correct.
