Wow! Just in the moment that I was setting all for going to sleep (here is now 4:35AM), I tried it one more time, with a modification:
** Setting a PROXY SERVER **
In iSiloX, into TOOLS|OPTIONS...|PROXY
I check the box in USE A PROXY SERVER, and used this address of one of the free proxy servers available on internet: 66.5.146.243 port 80
And now everything is working! Wow, again!
Then.. tomorrow morning I will recreate the script of the channel with all the sections of the first approach (and your suggestions).
Well seems that we finally have a solution.
