This seems to have occurred since the latest update had corrupted my CC and I needed to uninstall and reinstall all of my apps. This has been a very frustrating bit of work trying to get everything working again. Currently when I try to merge to HDR Pro in bridge (Camera raw) with three bracketed photos it starts and gets to the point where the HDR load screen would come up, but it just gives me a blank photoshop screen. Any suggestions?
I hope that someone in the know replies to this question. I am having the same problem!
