SO, temporarily, I had to rewrote everything to handle only text files, and 
now everything is working.

Hmmm - what did you have to re-write?  You should only have to specify
a different archive type when you invoke serializtion.

I think I took a look at the float which is part of portable binary archive.
I don't remember how that got in there.  But it doesn't look portable to
me.  Even assuming that

a) all floats were iee754,
b) that could trap all Nan's as errors

it would require providing conversion amongst 80, 64, 32, 24, 16 and 8 bit 
floats.
This is quite doable, but also a significant effort to build, test
and integrate to boost standards.
