unable to reopen saved file

[#1]

I installed the personal edition today on my laptop.  I saved the file in morning and now when i am trying to open the file to complete it its not opening and giving following error.

"Access Denied

This file was created by a licenced qlikview user and since you are using Qlikview personal edition you may not open this file. "

Below are other threads with similar issue with Personal edition refusing to open created by user with the same installation on the same machine

After looking at so many open threads complaining the same issue. I am thinking of giving up on Qlikview as its horrible to loose hours of work to logic bug in the application where the application is failing to recognize files created by its own installation and not ever shared thereafter.
