Loking in the WPIScripts I found out that the Config file had no extension. Changed it to Config. js and everything seems to be ok now. Sorry for a stupid problem. Now, how did the Config file loose it's extension? 'twasn't me, mate, honest. Swear on my mom's health. Now really, I think it has to do with the fact, that unlike with most programs, when one does "Save As" from the Confirg screen, WPI doesn't add an extension automatically, so it's quite easy for someone to end up with a saved file with no extension. Maybe this could be changed in future versions? Thanks
