Its working now!I mistakenly connected a 3v source to the 5v pin of the CPLD and when i moved it to its proper 3v pin it worked and i am now able to program it again.I do however remember programming it without connecting any voltage source to it just the usb cable to the computer, so that seems odd.Anyway thanks for all your help!!..im gonna go smoke a fat joint now.
