Hello,
could you provide us with a little more details about the issues that you are experiencing? Is there any series of steps that caused your problems? Could you try to get hold of your crash logs (Steinberg Forums) and post them in this thread or send to me as a private message. This would help us to identify the problem. It would also be interesting to have a look at the project that is causing the problems (you can import it on your computer using iTunes File Sharing).
If you have any further questions let me know or send me a private message.
Kind regards,
Frieder
