To reproduce:
1. Create a second newsletter, add sections in order to get some content
2. Go to the "send" page admin/settings/sunmailer/mail/x/send - x being the id of the newly created newsletter - or g
You get "Page not found"
3. go to admin/settings/sunmailer/content/
4. Try to add a section to any of the newsletters - nothing happens - you can no longer add sections
5. Delete the newly created newsletter - you can now add sections

Mike Wacker commentedCouldn't repro using the provided instructions.
In particular, I'm skeptical that step 2 could actually cause all that bad stuff to happen. The code for that particular pages doesn't do any database writes to any sunmailer tables.
If something got messed up, it was highly likely to be independent of step 2.
