 Hi
 Thanks for the feedback.
 Both suggestions work:
 a) I downloaded a 2016-version, and could easily open the file. Lots of
 variables with "_" beginning in file was there. 
Very good - do you remember what the original name(s) of the variable(s)
was, or was it exactly like this always (_DAY)?
It's maybe not important anymore, but perhaps there is an encoding
hiccup - I guess this is on Windows?
cheers
