Summary: update didn't completely install, now I can't open Thunderbird

Comments: 
First of all, I'm not sure this is the correct place to send this.  I
checked the FAQ and didn't find an answer to my question/problem so here
I am.
I got a message tonight that there were updates.  I told it to go ahead,
it was supposedly done.  I then tried to open Thunderbird - I get an
error message "A previous install did not complete.  finishing install.
 It has been saying that for the past 10 minutes but there is no
indication anywhere that a process is ongoing.  I tried a complete new
download w/o success.  Any work-arounds?
