Did you see any query names to import? Or simply table names? If you saw only table names then the FE really got hosed. If you saw the query, form, reports, and modules I'd think you have some corruption.
This is a suggestion if your object are displayed on the import list. Go to DOS. Move to the front end folder. From there enter something like
CD\YourDevelopmentFolder
YouDBName.accdb /decompile
Does that help?
