Can't load design for PCIe tab in BTS with transceiver starter kit

Okay, I'll head down the road of creating a design with the functionality you mention, but ...

In the meantime, if anyone can tell me why, within BTS 10.1 connected to the Cyclone IV GX Transceiver Starter Kit, clicking "Configure" --> "Configure FPGA with SMA and PCIe [with or without Loopback]" causes BTS to display the following messages:

Starting FPGA configuration...

Converting data to bitstream...

and then hang, or better yet, how to fix it, I'd love suggestions.

For example, my reading of the User's Guide is that BTS is supposed to automatically alter the design in the user hardware 1 memory to enable the SMA and PCIe tabs when I do the above. But do I need to somehow have used Quartus to convert and put bts_xcvr.sof into flash before BTS can "automatically" configure it? Or maybe somehow use btsXcvr0.elf?

My beginner's suspicion is that this is not an issue of hardware connections or board modifications for the PCIe and SMA connectors.

Looking forward to more thoughts,
