The log you posted starts with:

This log is only intended for user information.
It should not be part of a bug/problem report!!

so I do not know why you posted it, assuming you do not want to insult me.

-> Read the sticky and provide a proper debug output of what you are doing and I can look at it.

Also check whether the Preview works properly or whether it shows an error.
