Answer to new SXL problem?
I have only just come to SunriseXP myself, I'm now on Day 2, but I think I know the answer to your problem as I was similarly baffled myself until I RTFM.
When you open SunriseXP the first time you get a blank page. You then start a new site using Edit/New document insert.
When you have done that you save it to file using a name of your choice.
When you open Sunrise the next time it will show the file you just started.
Now to add a second site choose Edit/New document insert and add the details. Do NOT choose File/New SXL
You now see your two sites in the one SXL.
You can add as many sites as you like to the single SXL file.
If you want to make use of the other SXL files you have already made, open up each of them and copy the entry to clipboard. The open the "Master" file and use Edit/Paste Special to insert it in the list.
I hope this is the answer you are looking for.
