Discovery 4100 USB and SDRAM sample

The Discovery 4100 USB and SDRAM sample on the extranet that is to be used with the D4100 Explorer GUI will not run on the Xilinx ISE Version 13.4 as is. First, it has no .xise file. I put the project together and it wouldn't recognize the SDRAM Controller because it was done with a much older version of CoreGen, and it wouldn't upgrade it. I built a stripped down version to test the USB I/F but the GUI says there is NO DEVICE CONNECTED and there are still some issues with the FIFO source files.

Is there an existing project for the Discovery 4100 hardware that works with the D4100 GUI?

Thanks,

Gerry
