There might be threads for this already, but I searched several times and came up short.

When I EcuFlash doesnt mater the version, it does not have the definitions when I go read the rom, I click read and the screen that normally comes up with "evo base 7/8" lancer.... etc comes up blank. I tryed reinstalling, and deleted the OpenEcu folder, nothing. If I go to the folders and the xml docs are there..... below is a screen shot.....

 

Re post this in the EcuFlash forums you will get more help. I have had trouble uninstalling versions before. Every time you you install it it creates a backup that doesnt get deleted during uninstalls. I had to manually delete the backup and clean the registry plus disk clean and a reboot.
