Having trouble getting factory E40 ECM file to open...

[joshwho?]

I have a "commercial" EFI Live V2 and I double checked that everything is current this morning. I've licensed or registered the V2, licensed the ecm to the V2, saved the stock file, but I can't figure out how to open the stock file to scale injector size or do anything else.

I open the EFI Live "Scan and Tune" V8, click the "Tune" tab (F3) to open the "Tune Tool", go to "Open" and select the stock file and then click "Edit" (F5), THEN it says: "The version 8 calibration editor is not available yet. Until the V8 calibration editor is made available, you must use the V7.5 Tune Tool software to edit calibrations." ....so I click "Edit With EFILive V7.5" and it says in an Error window: "Can't exceute command: .\EFILive_Tune.exe Reason: File .\EFILive_Tune.exe not found."

I have tried it with two laptops and have had the same results. I hope I am just missing something simple! Thank you ahead of time for the help!
