Hi Jeannie, You detailed the reason in your last posting as to why you are getting the "administrator" message. I would guess that seeing your PC is a fomer store demo one, they have configured it for several users. Your solution, to take it back to them, is correct. They can re-adjust it for you.
As for backing up, you can just do this normally with PAF 5. Your file of 7,000+ people will be no problem. It will quite easily fit on one floppy diskette. This is because PAF compresses the data into a "zip" file. Even if your data base grows extensively, PAF will be able to handle a backup for you quite efficiently.
To pass on your data to other relatives, you will be able to do that on the CD (when you get the administrator problem fixed). You can do that either way - back-up or straight copy of your data. Your relative would need to have PAF 5 installed of course. They could then copy your data or restore the backup to the program on their PC.
You may be interested in this, too, which was part of the PAF 5 "Getting Started" info from Family Search:
"One of the unique features of PAF 5 is a feature that allows you to co-ordinate your research with other family members. PAF assigns each record in your ".paf" file a unique serial number. Like a record identification number (RIN), a unique record serial number identifies each individual in a ".paf" file. Unlike a RIN, a unique record serial number is unique worldwide. This means that each individual in each of your ".paf" files has a number that is different from all other individuals in all other Personal Ancestral File ".paf" files in the world."
"The uniqure record serial number does not change if you export a GEDCOM file and send it to another person. Therefore, you can send a GEDCOM file to another individual, he or she can import it into Personal Ancestral File, make changes to it, create another GEDCOM file, and send it back to you. You can then use the Match/Merge feature to identify the records that you originally created, identify what changes the other person made, decide which inforamtion to keep, and merge the records."
"You cannot see a unique serial number on the Individual screen and you cannot edit it."
This should help when you start to exchange details with your relatives.
