DRV8411AEVM: GUI connection

Tool/software:

Can't get GUI to connect properly to the EVM.  Have tried redownloading the GUI composer runtime and reinstalling the GUI.  Connected the USB cable first, then powered up the EVM.  The GUI does not come up at its home page, so can't select EVM type or update FW.  The error message is: CS_DAP_0: Error initializing emulator (error -260 @ 0x0).

Thanks.
