As I said in my original post, I am afraid to run the update, because I may get the same error, and not be able to start EFB again. The post directly above mine shows the exact error I got, when trying to run the update. ( abort-retry-ignore.) . I tried retry, and that didn't work. I was afraid to try ignore, and when I tried abort, it made EFB unable to start, both client and server..
