Error in preview mode changing pages

I have a course which has been running fine but have just changed by adding in some new pages. In preview mode it now freezes at the page following one of my new pages and then closes down Lectora inviting me to send a report to Microsoft.

I have tried deleting my new page, deleting the following page and changing the forward button but can not stop the error happening, any thoughts?
