I have a 25 slide module that stalls; I can't preview anything, publish, or even look at the player controls. When I try to preview, the progress bar gets stuck before the end. When I try to publish it, the progress bar moves slowly and then returns to the dialogue box. When I click on the player control icon it gives me the message "it is strongly recommended that you close any unneeded applications and save your project". Has anyone had this happen?
