GP 2010 cannot import FA Book - Error 10363

Hello

Client is on GP 2010 and have been attempting to import Fixed Asset Book using IM.V11

The following is the error:

SQL Procedure 10363 = Fixed Asset ID/Suffix ID do not match........

Tried to google, etc...

Left the suffix at Default - still errors

Typed in '1' and pointed to my file.

Any ideas??

Thank you.
