Are you in multi-user mode?
IIF import only functions in single-user mode. This means not only must other users be logged out, you must switch the program to single-user by UNchecking "enable multi-user" under the File menu or by quitting the server app.
Thanks a bunch....we had just set up multi-user and I did not know to switch!
