I've never heard of this happening before. Perhaps a LaTeX package got updated somehow and the new version is incompatibile with the old. It's hard to know without a minimal example .tex or .lyx file. For more information, please read: https://wiki.lyx.org/FAQ/MinimalExample If you can send a minimal example (please send all email to the list), perhaps someone can figure it out. In any case, sorry to your friend and to you for the frustration. I hope you're not on the hook for having recommended LyX :) Scott
