I reinstalled the 1.41b program disks, then Procedure Library Version 12 and then Productivity disk #7. The serial number now appears when I ask for Information in the NewViews shell, which is the same serial number that is on my invoice for the new products. But when trying to run a procedure I get “Cannot run unserialized library” and then “The prodedures installed in these books do not have a valid serial number. To obtain a procedure update with your serial number, please contact Q.W. Page Associates Inc.”
