Problems when customizing Player settings

Hi Everybody,

I engaged a couple of problems this week while customizing the player.

While creating a new story I opened a previously used Player. The player opened but the logo that I used before jumped to another place on screen or disappeared alltogether.  

I deleted the logo and replaced it with a new one, so far so good. Now I wanted to save the player and at that moment the player keeps crashing.

Does anybody know what to do, or what not to do?

Kind regards,

Chris
