Update to Sydney Pro Fails

I have been using the basic Sydney theme for about a year and I thought I would try Sydney Pro.
Install seemed ok but the text slider dissapeared from the front page the call to action button moved over to the left hand side and most significantly the Sydney customise menu freezes when I try to change anything.
All I could do is re install a back up.
Any suggestions would be welcome
Site still works fine on old free theme
Please help


Could you post a link to your site please? Your settings for the text slider won’t stay the same when you change to Sydney Pro, since it’s basically a different theme.
