apple aperture - no thumbnails after import

[Gary]

suddenly since sat night, any photos i import into aperture appear in the folder as thumbnails, but after i restart aperture they completely dissapear!
they are still stored as files in aperture but you cant see them.
all the files imported before sat night are fine.

any ideas?

Try rebuilding your library.

Press and hold Option + Command and launch Aperture and follow the instructions. Depending on how many images you have, it can take a considerable amount of time to complete
