Prebuilt application DXE doesn't load.

Hi, I'm trying out Demo application and example schematic as given in sigmastudio for sharc (ADSP-SC589) quickstart guide. I've followed all the steps in section 6.2. The example schematic is "Volume_Mute_Block_SC5xx.dspproj" . I'm having trouble at the SigmaStudio IC control window, wherein even after selecting Application DXE’ in SHARC0/SHARC1 tab, nothing happens. That is, the prebuilt DXEs doesn't load. Kindly help. Thank you.
