checksums have changed and file is not openable

[moesmopar]

hello i have a car here that was tuneable and unlocked before it came to me from another shop. I have been dialing in the tune for a while and now the customer took the car for two months and broght it back after getting new tires and a new upgraded fuel pump with no tune as i was supposed to tune it to work. when the car came in this time i went to download the current read from the car and it said the checksum values had changed and the file was not useable. what could have happened and how is this fixable? did another companies scanner change the values hptuners uses as the checksum and make tuning impossible at the moment without another unlock? i tried overwriting the entire for th ecar and it did nothing, i tried resetting my pc and my internet, i even bought a new laptop just to see and it still does the same thing. how can i fix this?
