VS700 Fantom Synth Midi Warning in X3e

So far I've had no response from Cakewalk support. After installing X3e Producer 64 bit, I'm getting the "Midi devices are not set up properly" warning again. The Fantom Editor comes up with the proper patches for the project, but plays only true piano sounds. It is necessary to open the set up Midi devices window and open and close all 4 slots. I can then load the proper saved instrument and it works right. I'm wondering if uninstalling and re-installing the stand-alone X64 version of the Fantom Editor would fix the problem.
