Hi Charles,
I uninstalled and reinstalled a few times. I couldn't rollback, because the older driver had never been installed. Every time I reinstalled (directing windows to the 1.0.3.0 driver directory) it found the later driver instead. When I installed by nominating the .inf file directly, it brought up the 'new hardware' popup when I connected the EVM.
I finally did it by choosing 'select a specific version', which offered me a choice of EVM and LDC1000EVM. Choosing LDC1000EVM at that point did it, and it now works.
Thanks!
