Thanks to All who gave assistance with my problem! I already had the new Prodigy Driver, however, I re-loaded that Driver AND the K3 Utility. Then, on advice from Walter, DK8KV, I downgraded the K3 firmware & then did a re-load - and now all is back to normal. Again, Thanks to All & 73 from the far north of ZL1. Mike, zl1mh.
