Trying to load the book (built via MobiPocket & tested on Kindler Previewer all fine) but when loading to KDP bookshelf keep getting this message." An unexpected error occurred. We have been notified and will look into it as soon as we can. Meanwhile please try again in a few minutes. We apologise for any inconvenience"
Got this message all yesterday & now today.

Have tried loading a simple .doc file which works fine.
Any ideas ?
