More Problems After Upgrade

This plugin is the perfect solution that I need for a client’s website I am building BUT I have run into some severe problems since the upgrade. I am using the lite version. None of the information for the images will update. The title and captions won’t save. Can’t save the link… I don’t need to open the image. Oh, and the size of the thumbnail won’t change. This was all working flawlessly. I went to change some images before we make this website live, and BOOM… I hope this is a quick fix because the client is ready to go live and I’m looking kind of silly. I have already uninstalled the updated version and reinstalled by uploading the zip file. Still having the same problem. Please advise. Thank you.
