Can’t export orders with current version

Hope you can help.

Since updating the plugin I’m unable to export my orders. I haven’t changed any settings at all. No matter how I try an export the orders, with or without the progress bar, I’m unable to export them. I get a page not responding or a dialog box which says prevent this page from making additional dialogs. I tried to roll it back to the previous version, but it’s not here. HELP PLEASE
