Was there any odd events leading up to this or one day it just happened?

The 000000000000 serial number problems was present in a now seriously old (we're talking late 2006) software release.

What version of the software are you running now? The latest release is 7.5.5 Build 83. If you are running a version earlier that 7.5.5 Build 72 then you must upgrade. The latest full download is here: http://www.efilive.com/index.php?opt...=48&Itemid=124. Then follow the instructions below the link to update to Build 83.

You must be running a version prior to 7.5.5 Build 72 you will need to uninstall all existing EFILive software and drivers. Before uninstalling please copy your ‘C:\Program Files\EFILive’ and ‘Documents\EFILive’ folders as a backup.

Once the new software is installed the latest drivers are in the ‘C:\Program Files\EFILive\Drivers\EFILive’ folder.

Can you also please send a screenshot of the 'Help->FlashScan V1 PCM Licnesing' screen from the Tune Tool with your FlashScan connected to your PC to support@efilive.com (me)?

i had a battery error when i first went to flash it. it errored out before it started flashing. so i drove it to work (30 min drive) and flashed it at work then these problems started..

i have since put a new battery in the truck as the old one was 6 yrs old. it now seems that the key on voltage is about 13v where as before it was about 11.5 i have re flashed with the new battery 3x now with no avail..

also the computer i am running efi live on was updated last night and it still didn't have a serial after a full flash. i didn't however update the flashscan driver as i didn't know we needed to.

i will post the screenshot when i get home from work. thanks

i flashed it again today and same problem. also it has a vin in the file but when read or scanned there is no vin.

i was going to flash the stock file back to the computer but afraid that if it takes the file and fixes the problem it may cost me a license?

sent the blx files off

I had the same thing happen doing a full flash a few weeks back, did it several times, i don't have the latest version but do have the previose one
V7.5.3 build 36

[akafred]

still no reply form anyone at efi live. i have sent off the requested info 4 weeks ago...

today i reflashed the original file and it is showing the same symptoms, it wont allow me to do a quick flash only a full flash.

do i need to replace the pcm? if so can the credit be transfered to the new pcm?
