Sorry gentlemen, I'm not a computer expert but I'm trying to help with what so ever knowledge I have.
L31Sleeper,
I downloaded your file (tun & ctd) and I got the same problem. However, I tweaked EFILIVE to force open the ctd file and here is what I got (Checksum error), there is something fishy with your files but I could correct it.
It is better to wait for an advice from software engineer instead of putting your ECM at risk
Kindly see the attached files to get an idea of you ctd files issue
Tuned Luck
