More info needed.
Can you open the database that you're trying to import from? If so, try compact/repair while in that database.
If not, try a compact/repair on it by starting Access and doing it from there (navigating & selecting the file to be c/r). Can't recall where this is in 2003 version.
Then retry the import.
Are you trying to import from an .mde? I don't think you can.
Rather than post your db in a file sharing environment, better if you can zip a copy and post it here. Some forum members won't download from a file sharing site.
The more we hear silence, the more we begin to think about our value in this universe.
