I think the validation is to do with whether the logger is on the IGC
secure list or not. Your Garmin isn't, so can't produce a validated file
no matter what you do to it after download.

.igc is just the format - the validation comes from the security built
into the logger (or not, in the case of Garmin GPSs, XCSoar logs from
PDAs, etc).

You only need validation for badge and record claims, so far as I know.

my files result in a "valid/green" score but the file won't rank my
flight. That's ok with me. At least the OLC accepts parts of the file
and it's fun to post them and see how I did for the day.

thanks,

I would see this in my earlier OLC days (before flying with an
official
igc logger). I used a Garmin eTrex gps unit to feed my PDA. At the
end of the day I'd download the trace using g7towin and save the file
as an igc file. OLC happily accepted that file, except that I'd get a
purple circle instead of a green one, but I would get a valid score.
For my silver badge flight I had to land at my destination and get
a signature from a witness.
