Head to the immo section and either match your ecu to the immo or disable immo entirely.

Also, please put useful information in your topic next time.

ECU p/n, motor type, vehicle, model year, etc.

You can compare your file to that original one and you will notice some custom code (and maybe relocated maps) at FF space close to the end of the file... (at 1E8000)
I think it's possible to "unlock" it: copy maps into original file and you will probably get unlocked tuned file.

Inside your file there are some interesting strings:
