USELESS plugin after update!

Hello,
we have a big problem after recent update. All galeries in old posts are messed up after update and slider doesnt work when i click on picture. It always open the picture in new window – what a shock. Also responsivity is gone and it doesnt even reflect what width i set for columns, it keep the same size….

Could you help me or my only chance is to uninstall it? maybe provide older version i can reinstall, but do the reinstalation correct already broken galleries in all posts?

Thanks
