This is usually a registry problem.
If the import/export wizards don't work at all, re-register ACCWIZ.DLL
If it's one or more file formats that aren't listed, re-register the
mstext35.dll (Text, CSV, tab-delimited))
In Access 2000 and later, the filenames contain 40 instead of 35.
To re-register a DLL file,
1) Locate it (usually all these are in the Windows\System32 or
2) Locate the file regsvr32.exe.
3) Drag the DLL file's icon onto the regsvr32.exe icon.
These problems are discussed in the following MS Knowledgebase articles
or for Access 2002
