I have an assembly whose values are taken from a text file in a windows folder, but interestingly: when I rebuild/renew the assembly, it reads the parameters from the text file but after then the most of the parameters that once were in the text file, disappears(erased)..

 And when I pack and go the assembly, the same weirdness happens..., in the target folder with new assembly, the text file won't have the most of the parameters..

What might be cause, How can I overcome? if it isnt a solidworks debug issue..
