G'Day Vin,
Don't give up - one more try. You have not said what Windows OS you are using.
I ran a few tests with my Win 10 systems, and got what seems like some of the errors you are experiencing.
But first, you need to make sure you have a clean sheet. OmniRig is a "software server" - one can easily end up with multiple copies running. And also, Client.exe, one can strike a few errors and finish up running several copies which may or may not be holding the com port, preventing Logic from working correctly.
If we add "Run As Administrator" into the mix, all sorts of issues may arise.
Make use of Task Manager to remove client.exe, amd OmniRig between tests, or reboot the PC. Always start with a clean sheet.
You should be running LOGic "AS Administrator".
If I run CLIENT.EXE "As Administrator", and I run LOGIc "As Administrator", client.exe shows the status updates occurring as I wind either VFO, LOGic moves the rig with the Spot log etc, etc. All works as I expect.
But, if I run CLIENT.EXE as a normal user, LOGic errors, I get multiple copies of client.exe running - errors all over the place. Clearly everyone is fighting over control of my COM ports.
Your sequence should be ....
Reboot the PC (or clean out old copies of client.exe, OmniRig with Task Manager)
Wait for MicroHam Router to be setup and functional
Verify you are running the correct K3 driver in the MicroHam Router.
Rotate VFO A and verify status change by looking at the PORT dialogue in Microham Router
Run CLIENT.EXE "AS Administrator"
... verify status change in OmniRig by rotating VFO A or B.
Run LOGic "As Administrator"
Good luck.
