    Flashing ecm

    Can someone please tell me what I am doing wrong. I have a 411 ecm from a 5.3, I am installing it on a 98 l31 5.7. I downloaded the file, bought 2 credits and started to flash it to the ecm. When I go to write to ecm it says that the vehicle isn't licensed but I just payed for and used two credits. Why would I have to buy more credits. I thought it only took 2 credits to flash a gm ecm.

    Impossible to say without the file & infolog, please open a support ticket for one on one assistance.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    I have 2010 GMC that I need to replace the ECM. no mod needs. (new from AC Delco)

    ECM: 7E8, CAN, ECM -EngineControl - E38, GM Gen4 V8
    2010 GMC Sierra ? ton SLT, 6.0 L, 8 Cyl

    I read the ECM only, save the data, turn off the key. replaced the ECM and now I am trying to the file.
    I tried "write VIN,Tunerlock,VATS" and it says unlicensed vehicle".
    I tried "write calibration" and it says unlicensed vehicle".

    What needs to be done at this point?
