Hi Terry:
It sounds like you have two programs opening the same com port at the same time. Windows does not support that.
First of all, a trick to save you time in testing. When LOGic locks up due to Com port conflicts, kill it using the Windows task manager. Then kill whatever else has that same port open, and then you can run LOGic and change the Com port settings. You may also change the Com port settings by editing the file RADIO9.INI (or ROTOR9.ini) in the LOGic install folder with any text editor. That would be the option to use when you cannot get into LOGic.
OmniRig allows programs to appear to share a com port, but that is not what is happening. OmniRig has control of the Com port, and LOGic and other programs communicate with OmniRig using direct program-to-program communication.
Here is a video on setting up OmniRig
