how do you set up the dspbuilder license? 

 My steps: 1. get the valid license ( i.e. dspbuilder_lic.dat )according to my MAC address 2. add a system variable LM_LICENSE_FILE , edit the value <path>/dspbuilder_lic.dat.  if there is already have LM_LICENSE_FILE, append ";" then follow <path>/dspbuilder_lic.dat  see DSPBuilder\Doc\UserGuide.pdf P246 for more infomation.
