I have the same problem... same message appears every time I save...
when clicking on the magnifing glass icon a web browser page appears that shows the invalid elements...

Try this:

Go to 1. Story.
Select All Roofs (hopefully this will select even the buggy Roof even though you cannot find it).
Cut to Clipbaord (CTRL+X)
Paste back.

During pasting ArchiCAD usually tries to fix incorrect element data.

This may work.

Thanks Laszlo, I tried your suggestion but it didn't work.
I found the invalid elements from the 3d window error message and deleted them. They were more than 10, but anyway I solved the problem.

I had similar issues here! I select all roofs (in 2D because there are errors in generating 3D), then deselect every roof + use F5 to check what roof was cause error. It's sound like a "manual way" but it worked!
