LyX crashed and now doesn't work

[Lee Bradshaw <lee@sectionIV.com>]

Hi,

LyX crashed while I was playing with the Math Panel. Now it only sees
two available textclasses in layout/document/class. Both are SGML and I
was using the default article class . I purged and reinstalled LyX, but
there was no change. Here's the error log from trying to generate a dvi
file:

  freefall ~ $ lyx firstlyx.lyx
  LyX: Unknown textclass `article' [around line 3 of file
  ~/#firstlyx.lyx#]

The article.cls file does exist:

  freefall ~ $ ll `locate article.cls`
  -rw-r--r--    1 root     root        19639 Mar 23  1999
  /usr/share/texmf/tex/latex/base/article.cls

Should I try to purge/reinstall the tetex packages or does anyone have
a better idea?
