Sorry can't load this project...

I created a track in the latest GarageBand (10.0.2)

Then if I try to open it in the latest Logic (9.1.8). I've tried both right-click > Open and Opeing from the File menu in Logic.

I get the following message:

" Sorry can't load this project because it is created by a newer Logic Pro version "

but it does go ahead and create the folder and the file. When I open the file it's an empty project.

Can anyone tell me how to open the Garageband track in Logic Pro?

Thankyou.
