Applescript cannot find Filmaker File

I recovered a filemaker database and tossed the old one away and renamed the recovered file to the previous name. Now my applescripts that refrence it error out and say: “File /Applications/FileMaker Pro 6 Folder/Dish USA Core/DISH USA INVOICES.fp5 wasn’t found.”

the script is:

tell application “FileMaker Pro”
launch
activate
open alias “/Applications/FileMaker Pro 6 Folder/Dish USA Core/DISH USA INVOICES.fp5”
Do stuff
End tell

The location of the file did not change. Why can’t it find it now?
