In that case, I'd check that your script has really changed the data to 
be written to the file.

on setPref prefName,prefData
   put prefData into preferencesData[prefName]
   put the keys of preferencesData into theKeys
   repeat with x=1 to the number of lines in theKeys
     put line x of theKeys & "=" & preferencesData[(line x of theKeys)] 
&cr after newData
   end repeat
   put newdata ## CHECK HERE that the data is what you expect
   put newData into url ("file:Preferences.dat")
end setPref

Also, when you say "every time afterward it will not write anything" do 
you mean the file remains as it was before or that it is empty?
