As I stated in the other thread, I got the CPLD programmed in another REX board. This was my first time using the Xilinx labtools in Win 10 and it didn't work out-of-the-box. Luckily, there's a good recipe for dealing with this. ISE isn't supported anymore and isn't supposed to work in Win10, but a quick DLL swap seemed to get it working for me:
