Running on a macbook pro.
Purchased through the apple app store.
Worked fine prior to mavricks update.
I have read where others have had this issue, the general response has been that they have had no support from adobe in resolving the problem. One guy said he managed to get issued a new download of the softwear that works fine with mavricks.
so there is a fix avalible but for some reason its not been a general update for all customers with premier elements 11?
resolved and received a new download
