Update 1.2 ship designer issue

Soooo...... About to finalise my own ship set and then updated to 1.2 and the ship designer will not recognise the majority of the designs that I created after days of work

The designs are still in my C:\Users\Documents\my games\GalCiv3\Designs folder but the corresponding .png files are black?

Anyone else had this problem or can help?? Recreating everything can be done but I really don't want to ha!
