I upgraded to v 2.18 last week and got the folowing errors after adding books. Now the error comes on startup and nothing seems to work.

Does this mean that my library is corrupted?

Answered my own question, that library was the problem. Another one worked fine. Thank goodness for weekly backups! I'm Happy once again but I would like to know How it Happened
