Both operations work for me on my PE.

For the Email as PDF, ensure there isn't already a file in that folder with the name you're trying to give it when doing the Email as PDF. If the Journal can't overwrite the existing file, it could cause such a problem.

I have noticed a couple of forum users indicating that Library and email operations report strange file system errors. I'm wondering if the Ermine update changes some of the locations and/or file/directory permissions. Yet for most people it's not a problem (I think). Again, your two issues are something that really only Tech Support (Level 3) would be able to help you with as it doesn't sound like you're doing anything wrong.
