TeX says it is stymied and format does not match pool, or something
I did an update on cygwin and then when running LaTeX got an error message something like:
(Fatal format file error; I'm stymied)
and it said that a format did not match the pool, or something (the error message scrolled off the buffer and I can’t see it any more).
This seems to mean that there’s been an upgrade and the formats need to be regenerated. I am using TeXLive on cygwin, and what I did was this:
texhash texconfig confall texconfig init
and latexing the document only worked after the third step. I don’t know if all were necessary, but this did fix it. This is well known, but the trick is not to panic and start reinstalling things and suchlike…
