stage 2 tune file wont fully write to the ECU
 

I just got a stage 2 tune from M7 Speed, its their Maxxboost tune. Ive had no issues with setting it up until this point. i downloaded the tune file that they sent me, uploaded it to my tuner module, plugged it into my OBD2 port, put the key fob into the ignition in the "key on" position and started the writing process of the stage 2 tune file. its at this point that it tells me there is an error writing the file to the ECU. Im just curious if anyone else has had this issue with their tune file and if there is a fix that i can perform. its a friday and ive been waiting for awhile to get my new tune installed in my car and now i hve this stupid problem and im not interested in waiting til monday afternoon to start the troubleshooting process with M7. I want my tune in my car ASAP. somebody please assist. thank you in advance.
