I installed VCM Editor on my desktop so I could edit my tune on my nice PC which has its document folder synced with the tablet I use to run vcm editor/scanner in my truck. But it won't let me save the changes to the tune file. Is that intentional? I thought the licensing was done when you wrote to the truck. Is there some way to work around this? I would sure rather deal with a bunch of tables and what not on the large monitor and big keyboard at my desktop machine.
