I did the firmware upgrade to 3.0638.0.0.1 by changing the product code via Nemesis. Everything came back from the restore perfectly except the (built-in!!!) Quickoffice which now refuses to run.

When I try to run it I get the message "Menu: Unable to execute file for security reasons". This is a complete pisser 'cos I've actually paid for the upgrade to be able to edit the spreadsheets and I've been using it A LOT.

Can anyone advise me how to get my spreadsheets back?

What is Nemesis? IS an official Nokia agent? If Yes, they or another Nokia Service can handle that. If is another way (not official) way to do the job, You have a problem... Try a phone soft format and see what happens!
