Hi Lean, The version of various components of the development environment can be quite tricky to deal with - many of them are not back-ward compatible, unfortunately (including Matlab, Xilinx, and Casper libraries). But your Matlab & Xilinx versions look fine to me. Looking at the error message you got, I suspect it's a Casper library related problem - which version of CASPER library (mlib_devel) are you using? If you try a fresh copy of fft_wideband_real from the library browser (drag the fft_wideband_real from the library browser and drop it into your design, change its parameters to those that you want, and delete the old one), and do a ctrl-D, do you still see this error?
