Dear Ziad:
I assume that you chose "2. Make data file" after adding the two new fields to the QES file. This will over-write your existing REC file with a new empty REC file and all your data are lost. There are two ways to prevent this:
1) After you changed your QES file, go to "4. Enter Data" and open your existing REC file, and you will be prompted whether the REC file should incorporate the new structure (it checks for the date of the QES file and sees that it is newer than the REC file). As you only added fields, there is no data loss.
2) From "Tools" choose "Revise data file" and you will be prompted for the name of the QES file
Either way gets you to the same result with your data preserved.
