Just noticed your EFTPS password expired link - this one is not actually related to the thread about the crashing of QB and inability to file or pay MD UI through QB. 

EFTPS announced a new protocol last year - if you file through a 3rd party (i.e., QB payroll), your EFTPS password will expire every 13 months and must be reset.  When you log into EFTPS directly, it doesn't tell you this!

So you will need to go onto the EFTPS website, under My Profile and change the password every year.  Then you will need to update that password in QB when you are sending the next payment.  I'm setting reminders for all my clients who use QB Desktop payroll.
