Hi Laura That is rather strange as the Xilinx Counter block does have a mask parameter named 'implementation'. Basically, when using the Virtex5 architecture you can specify that the counter be implemented using a DSP48E slice instead of logic. I use this to reduce logic use as there are generally many DSP48Es spare on the ROACHes.
I would suggest dropping a fresh FFT block from the library and setting the parameters as needed rather than updating an existing block, newer scripts may break on older blocks and this block was updated reasonably recently. If that doesn't work send me the design and instructions on how to break it.
