Acrobat Reader used to work just fine for me, then suddenly stopped working, crashing whenever I tried to open the progam, and giving an illegal operation shut down, and an error message about not finding an external window handler (or something like that).  I was having this problem with an earlier version, so I upgraded to 5.0, hoping that would help.  I'm still having the problem with the illegal operation shut down, but I haven't been getting the window handler message anymore.  The error details I get with the shutdown are:

Anyway, the end result is that the program simply does not work any more, even though it used to.  Any idea what is wrong or missing?
