lost imap folders, cannot recreate account

[jim galley]

Rebooted system and noticed that whenever I sent an email from imap it would never save into the imap sent folder - had to manually move it. Error message was something about imap i/o error.
Attempted to change the impap account settings to specify the sent folder on the imap server.. Once I made the change, the account disappeared from the main UI (couldn't access any the account folders / messages) yet the account settings were still visible. Rebooted system - same issue. checked the disk - no problems. ran evolution from terminal with the following:
