I'm trying to open the tune repository and I have a pop up window telling me I don't have the correct operating system. Is this referring to the 3.6.26 version and going to the latest 4. something? I read a few discussions about this and even for the PRO HP tuner seemed like it caused them a big headache. I'm trying to open a stock tune in the tune repository to compare some parameters. I also read that this particular upgrade was free. I currently have the previous interface, PRO version and I'm fine with it. I was reading that I would have to upgrade that also.
If someone could give me a run down on what I need to do or direct me somewhere that has a fairly detailed guide of how to do this.
Thanks
