what does this mean?
 

so i got my megasquirt in yesterday and i havnt installed it into the car yet.

i pluged in the usb cord to the MS and into my computer to dowload the driver and then i opened megatune to just look at how its set up(i just downloaded it minutes ago) and this poped up

Attachment 196451

and i have no idea what it means but when it says "this is usually a very serious problem" it kind of makes me worried


right now the usb cord is disconnected and it still shows the message when opening megatune

when i click on "no" megatune opens... when i click on "yes" it doesnt open

0x53 usually just means you're on the wrong COM port.
