[casper] Licensing dsp tools 10.1

[Daniel Esteban Herrera Peña]

Dear Casperites,

I'v been having troubles synthesizing the spectrometer, so I wanted to 
try a different version of every tool I'm using (Ubuntu 
Lynx/Matlab2009b/Xilinx 11.4 to WinXP/Matlab2007b/Xilinx 10.1) but I 
can't have dsp tools installed, I installed Xilinx Webpack 10.1 and I 
execute the dsp_tools installer, the program ask me for a registration 
ID (I use what xilinx gave me for webpack) but that is not the right 
one. I can't even have a 30 day trial, so my question is how did you 
guys can work with this old version for free?

Kind regards,

Daniel H.
