I have read the other V1 to ctz thread and have a question.

I updated my home and work laptops the other day with the July 7th builds. My V1 unit will not flash a ctz file on either laptop. Did this update render my V1 unit into a $550.00 scan tool. If so, what is the newest version of 7.5 that I can use with my V1 unit and .tun files. It appears that even when you open a .tun and make a change and then "Save As" that it is saved as a ctz file with no option of saving or converting it to .tun.
If I need to I will uninstall EFILive and go to an earlier version on one of my laptops so that I can use my V1. I will leave the other laptop updated and use my V2 unit on it.
