I am selling my Hptuners Pro cable and I am trying to help the person buying the cable from me. I gave him a screen shot of the serial number and application key under the information tab of vcm editor. Vcm editor says that it is the 2.1.18 version. The buyer tried to create a new account by entering the serial number and application key, but it says that it is an invalid application key.
If I gave someone at hptuners the information I have is there any way to verify if the serial number and application key are correct? I sent an email to support@hp[tuners about it yesterday, but no response yet.
