Hi Kry, thanks to you too for your excellent support.
This was the same file, but if I try to download another file, it happens the same. It happens for EVERY file I try to download!!!
I'm not waiting for some magic answer / solution....just some clue from you, who know better than me how the program works when it calculates hashes, etc ... How to debug it, etc, to try to find which program/part of program is responsible for this failure. Perhaps it's just a corrupted shared lib!
Thanks anyway, you guys rock
