>When I attempt to pack a table which has been in use in an application I get an errror 41 (fpt file missing or damaged.) The table is present and the application seems to use the records in the memo file correctly. Is there a way to repair this (seemingly unbroken) memo file

If you can USE the table, you should be able to SELECT * from it into a temp table - then ZAP the original, and APPEND FROM the temp table. Only thing is, in my experience, you will lose information in the memos.
