project security problem

One of my users is having a problem that I suspect is a security issue.

This user is in the habit of 1) creating a new project, 2) exporting the project to Excel, then modifying the XLS file, then 3) importing the XLS back into P6 and updating the original project.  Recently this user was downgraded from "Admin Superuser" to another security level.  Now the user cannot complete the import process.  When she attempts to import, she is prompted to select a project to update...  this list of projects is empty.

Please help.

Thanks,

Dean
