I've Googled (the verb   everything I can think of in search for a remedy to the problem, and only find (end up here) this thread. So another user with the error Failed To Upload Settings / Curve is not one-to-one. Initially was running an older version (1.0.30.1) upgraded to latest 1.0.35.2 --> same-same. Strange, everything works; downloading from device, upgrading device firmware (Reuleaux DNA 200), I can even lock ohms when I select the chk-box for 'Ohms-Locked'??? All the tools seems to work fine reading all the parameters ... Tried uninstall / re-install. Tried the 'compatibility to Windows 7' thin to no avail; run as Admin ... nope. New USB cable ... As soon as I connect (the working device) and hit the 'Upload Settings to Device' button, I get the error (no changes in any of the settings)? From the device itself I am able to make changes to all the settings available (so I'm kinda 'assumin' the device is OK). Anyone find the source of the issue and a fix? I'm kinda at a loss; Any Ideas !?! Failed To Upload SettingsCurve is not one-to-one.
