I'm getting an error message (screenshot attached) when I try to open the attached doc:
I know this is a known issue (eg viewtopic.php?t=105747) and that there is a tutorial for fixing it (viewtopic.php?f=71&t=87180) and that I should update to LibreOffice (I will!). But the tutorial is a little beyond me (I've tried), so I wonder if there is a kind soul here who would have a go at fixing this doc for me. It's a couple of hours work bound up in there.Read error
Format error discovered in sub-document content.xml at 2,4032(row,col).
Thank you in advance,
Julian
