Macros problem with XP

For SEVERAL years our accounting department has been using macros set up in
Excel to import data into our Peachtree Accounting software. (I did not set
these macros up, nor know how to!) We recently got new computers that have
Windows XP Professional. When we try to run the Macros the following error


comes up: "Remote Data not accessible. Start application 'PEACHW.EXE'?" Even
when you click yes, the following message comes up: "The Peachtree accounting
program must be running in the background before running this function.
Start Peachtree then try again." I have tried having Peachtree open, closed,
just about anything I can think of. I don't want to change the macros
because they are working just fine for our Windows 98 machines. Please help!
Let me know if you need additional information. Even our IT consultant is
currently stumped. ~Gretchen
