Dear Sir,
As far as ISE errors are concerned, there is nothing we can do. You can try to open a webcase with Xilinx and ask the questions to them or use google to do that.
Another option is to purchase an engineering support contract where one of our engineer could go through the firmware design basics with you, let me know if this is a path you are interested with, this should be discussed with sales and I can arrange that they get in touch with you.
Thanks,
Arnaud
