Hi Tom McDuffee

When you opened your Punch program, Punch opened a file called "Untitled 1", then you opened your file called (for example) "myhouse.PRO". You worked with your file--> you saved your file and when you you tried to close the program, Punch asked "Save changes before closing?". Punch was asking about "Untitled 1" (empty), so if you answered "Yes" and then "Save as"--> "myhouse.PRO", then you saved an empty file.
However, there is a way to get your work back (probably). This is the way it works with the Windows version--> Go to your Windows Explorer--> Program Files--> Punch! Home Design - your program--> Data--> you'll find 25 files called ProDataX.dat (X will be a number ProData1.dat, ProData2.dat, etc)--> copy these files to other folder--> rename each file as *.PRO--> ProData1.PRO, ProData2.PRO, etc
