[Opening saved .lua file w/ builler]

Haven't had any luck opening my original file, but I was able to cut and paste my data from a notepad file and start another one. Do be honest, I believe that until "Wherigo for Dummies" book is published they are out of my league. I now know who they are so few and far between. Not like building a Geocache at all. Thanks for help

[Opening saved .lua file w/ builler]

I worked for a couple hours, and now I get this error when I try to reopen and continue working on

 

Error message:

 

Error Reading Cartridge.

System.ApplicationException: Exception of type 'System.ApllicationException' was thrown. at Groundspeak...

...at ZonesAuthor.frmMain.OpenCartridgeFile()

 

What is up?

 

Thanks
