Hi Derek,

Unfortunately, we couldn't recover the file. So I'm updating a file that was saved under another name, and has data up to end of last month - so not too bad.

I think that's what I'll be doing from now onwards: saving under another name every month.

Anyway, thanks for your quick and kind support!

Hans.
