Sorry to bother again, but, since I formated the Hard Drive, some odd things had happened, nothing (I hope) to call for help... but I come here because this is something that I can't fix.
THe F keys suddently stop half of their work, because the first keys I configurated worked fine (F1, F2, F3, F,5), but when I pressed another in order to set it, nothing happened... I trashed the preferences, and seems that it fixed the problem, but... in the middle of the task, a bomb with an error 10 appears, then I restarted, tryed again, another error 10, restarted, and things are in the begining... the configurated keys function well, but not the option of setting the other ones....
Thanks again for your time and your help
