Open files from soundbooth cs5 in audition cs6

Hi,

I had some old project that I worked on soundbooth cs5.

Now I have audition cs6 and I need to open this project which extension is .asnd.

I already search about this problem and I only find this: How to open ASND files?

It worked in some way, I can unlock all the files that are within the project but the project itself no longer exists. I would have to make the project all over again.

Is there any solution for this problem?

Thanks
