OK, thanks, reinstalled original version, then removed it properly as per your email, then installed new version, and it installed ok. It shows up as the latest 2013 version and appears to run ok, showing the bios settings.
However, when I run it and select the tuner tab, I get the frequency tab, but don't get the ratio and voltage tabs as shown in the help, so can't change these.
Anyone any ideas about why? GA-78LMT-S2P on win 7 64 sp1, with latest f4a bios
