How do I Save/Open my map?

I made a map, and I saved it. Now when I try to open it again, all the panels are grey, with red borders, could someone help me with how to open my map, with the panels looking normal?

I don’t really recognize your problem. Could you show a screenshot?

Problem

This is what it looks like

It looks like it couldn’t find the image files referenced by your tilesets. It should show a warning about this when you open the map, did you click that away?

This problem usually happens if you change the location of the map or the images relative to each other, or if you accidentally refer to images in a temporary directory. In any case if you click on “Edit Tileset” you should be able to correct the image file references in the Properties (Tileset -> Tileset Properties…).
