I bought my MS used almost a year ago. Its MS2 extra with 2.0.1 firmware. I recently installed the harness with all sensors and splices done. I have the stock ecu running the injectors and coil. When i crank the motor over none of the leds come on and neither when the car is on. I know one suppose to flash when the engine turning over

Heres my problem, when i connect the ms to my laptop I get a pop up saying "The selected communication Port (COM1) Cannot be open. To fix change port and try again." I tried all combinations a nothing happen.

All so i get "MS cannot connect to controller page1-5"

Sorry if this is straight forward enough i don't post much.
Any help appreciated.
