Cannot see new emails

When I switched my computer on this morning, Thunderbird refused to dowload new emails. Nothing I have tried solves the problem. A message in Crash Reports says:

"Shutdown hanging at step XPCOMShutdownThreads. Something is blocking the main-thread".

My copy of Thunderbird is up-to-date and accesses two accounts (Gmail and my university account (IMAP)). New emails are missing from both.

Any advice on how to solve this problem would be appreciated.

Thank you,
