! \textfont1 is undefined (character 120).
l.16 \setbox0\vbox{D $$x$$
E\par}
Somewhere in the math formula just ended, you used the
stated character from an undefined font family. For example,
plain TeX doesn't allow \it or \sl in subscripts. Proceed,
and I'll try to forget that I needed that character.

! You can't use `\vadjust' in vertical mode.
l.22 \vadjust
{K\par}
Sorry, but I'm not programmed to handle this case;
I'll just pretend that you didn't ask for it.
If you're in the wrong mode, you might be able to
return to the right one by typing `I}' or `I$' or `I\par'.

I expect to see \noalign only after the \cr of
an alignment. Proceed, and I'll ignore this case.

There should be exactly one # between &'s, when an
\halign or \valign is being set up. In this case you had
none, so I've put one in; maybe that will work.
