Ok ,I was having trouble sending any changes to the ecm.It allowed me to do everything else but that.I kept getting a timeout error.I eas told it was doing this because I was running the program on a shortcut through windows.So I took windows completely out of my laptop and installed DOS 6.21 .Thenre installed.Now I can read whats in the ECM but I cant sve any files at all.I keep getting File Not Found.It also says this if I try to edit file or sve any file.Please help.I've been messing with this thing for months.Thanks Tony
