Issues with Com Port already in use in ReplicatorG on Windows 8.1

If you having this issue and have already gone through the whole bypassing of driver signing process AND you have installed Makerware at some stage try the following:

Load Makerware, Select Services, Stop Background Service.Close Makerware
Then Load ReplicatorG and Connect to your printer.
I had same issue with a Mbot Cube 2 (old original motherboard 7.2 firmware) and Mbot Cube Single (7.5 Firmware), but NOT when connecting to a Prusa I3. Unsure if any other Mbots will have same issue.
Have not found how to kill it permanently. Will provide feedback when I do or maybe someone else will.
Solution found in this post #5. (
