Could be the reason i assuming is
1) If some one open the application where you created and they save the application from Licensed machine. Could be you are trying that, That is not possible because you mentioned you are using personal edition
2) Then, second bullet may be the cause file corrupted. Even if file corrupted the error you are showing is won't show
3) Final way, I am thinking can you try 3 Tier architecture for that file and check the file whether data comes to the Tier-2
-- Create one more application
-- Load the existing qvw to new qvw by help of Binary Load
-- Please check whether the data coming to new qvw or not? Then we can talk what was the issue, If you would like to share the application.
