Problem in connecting ccs v4.22 and Simulink for c6000

Hi, I am using TMS3206713 kit and want to connect this kit to simulink in Matlab....as the kit is old I am not getting the software ccs v 3.3 or higher anywhere on the internet...

while using ccs v 4.22... I am not able to connect this kit to the simulink in Matlab 2012...

If someone can help either getting ccs v3.3 or connecting the kit through v 4.22 then I will be obliged...

Please Help
