When I click on "Read messages," I get no response and my mail folders are not appearing in the left viewing pane.
They were there last time I opened T-Bird, but when I started it up this time, they were gone. I have already closed the application and re-opened it and that didn't work.

So it is...my bad. There is/was a bug report for exactly your symptoms ("Unified" folder view blank), but it was closed as being caused by extensions. That was going to be my next suggestion -- to start TB in "Safe Mode":
Are you (or were you, with 3.1.2) using any extensions ? If so, which ones ?
If you get an opportunity, and are so inclined, you might be able to help us figure out why this occurred.
Reinstall 3.1.2 using the same steps you did when the problem occurred. Start TB and go to "Tools->Account Settings". If you see your accounts, skip to Find prefs.js.
Reinstall 3.1.2, then go into the Configuration Editor:
- "Preferences" (Mac/Linux) / "Options" (Win)
- Click the "Config Editor..." button (lower right)
- Click the "I'll be careful, I promise!" button
- Type (without the quotes) "ntmanager" in the "Filter:" textbox
- If the "mail.accountmanager.accounts" variable lists multiple accounts, continue with Find prefs.js, below
- Close the Configuration Editor window
- Close the "Preferences"/"Options" window
Locate your profile folder; if you don't know where it is, see:
For each profile (if there is more than one), locate the 'prefs.js' file in the profile. If you're not sure where to find 'prefs.js', see:
Make a copy of the 'prefs.js' files and save them elsewhere, naming the files 'prefs-1.js' for the first profile, 'prefs-2.js' for the second profile, etc.
Reinstall your "working" version of Thunderbird.
If you don't want to do this, that's perfectly OK; but it would be appreciated. If you do decide to do it (no hurry!), post a reply indicating whether your accounts were visible in the first step, above.
