PDFs causing my CT3 to close

So I am the admin and i am the one who reviews and publishes drafts - all of a
suddent his morning, if someone sends me a PDF file, i can't publsih it. i
click on the page title in the draft console and Contribute closes - no error
message, no nothing. Just closes. I can't delete the drafts from the manage
sent drafts either. Any help would be so appreciated. I already uninstalled and
reinstalled as well.....

Thanks!
