Ok I just put the Lights Out Script 1.4 in my MXM.xml like this:
<Title>Lights Out 1.4</Title>
The lightsout.xml and overlay.png is also in the scripts folder
The error I get is this:
ERROR (line 1): (callfile) "ActionScript file failed execution"
This same error has also occured with a few other scripts I tried like FileManager, IP Dialog, Text Editor, and maybe a few more
