Hello

I want to create programs for Lego Mindstorms NXT kit in Simulink. I tried to install support package for Lego following that tutorial. Everything goes fine until downloading process of package's files - after some time following error occurs:

I tried agian few times, my network connection is fine, but problem still happens. Is Lego support package out of date? BTW, are there any other addons for Lego NXT support in Simulink?
