It's a bug in the program - you shouldn't be able to trigger that message
whatever data you feed in.

Unfortunately I'm now in Australia until June.  Mike Lake has lent me an
internet connection, but it's badly lagged to the UK.  Maybe I can take a
look while I'm over here, but otherwise I'm afraid the only workaround is to
drop back to 0.91 (which isn't on www.survex.com any more - if anyone needs
it mail me and I'll see what I can do).

Cheers,
Olly
