Problem with flash programmer

I have followed step by step the AN370:

-Conversion sof=>jic (with the compression, that is not mentionned in the an)

-Generation of a SFL megafunction

-Loading of the .jic

This error remains when I try to load my .jic: error: can't recognize silicon id for device 1

But I have a question about the SFL megafunction:

When has the configuration been loaded to the FPGA in these step??

I have generated a VHDL file ( and a .cmp) but I never used it...

Or maybe it´s a malfunction case as you said in a previous post, but in this case I don´t know what else I can do...
