Hello. Mavericks and Interactplayer / Interactbuilder

Hi!  In the recent month I have been working in a iMac 10.8.5, 3.1 GHz, Core i7 with 16 GB.  Both, the Builder and the Player run fine.  This morning, I updated my previous Air 10.6.8 to Mavericks, as I read that the new system would be faster and more efficient.  However, when trying to run the Builder and the Player I found that both have some issues.  The common one and that I find relevant in terms of timings for animations, etc is that both of them, either in the Interact mode or in the Player itself run very slow... Before installing Mavericks I was able to see my app in the Player of the Air.  Any recommendation?

Many thanks!
