MC1321x is a bit old and it used to come with CW 6.2 originally. However, this has changed and actual codebases only support CW10x. Also, the BeeKit version that came with your kit might be old too. I would recommend you to download it form our website (it is free) in order to have the latest release with codebases supporting CW 10. You may also download and install CW 10.x in your PC. You should not have issues with that.

Moreover, MC1321x devices used to support full ZigBee stack a while ago but due to ite current implementation, the MC1321x memory footprint is unable to host it. You may use another 802.15.4 based stack such as SMAC, MAC or RF4CE, but ZigBee is no longer supported. Here is a document explaining the differences between stacks:
