Hello everyone!

There's this error popping-up whenever I open a newly created xaction file using Design Studio 1.6

The xaction file is for the report that I created using Report Designer 1.6. Whenever I open newly created xaction files, I'm being prompted with this message:

"An obsolete file format has been detected. This may cause data to display inaccurately. Update to the latest format?"

I just click 'Yes' and continue what I want to do with it.
I don't have any idea what the cause is, and why, so I decided to post it here in case anyone can tell what this means.

BTW, i'm on Windows platform.
