I got a Dark Core SE and it failed to perform and update when setting it up and has been a nightmare since. I am using this on a work computer which I got the IT department to install the software on for me so I can't uninstall and reinstall without bothering them to do it again. I have tried to do a reset of the mouse. I have tried to force the firmware update. It doesn't do anything. The mouse is functional but I don't have any hardware profiles showing in the iCue software at all. The mouse also acts completely different when plugged in wired vs wireless. I am tempted to just return it to best buy where I bought it and set up a new one but not sure if the new one will work properly or not. It seems this mouse is a nightmare for firmware updates and not one of corsairs better mice. Is there anything else I can try before I return this thing? I have contacted corsair and they said to force the update and browse for the update image but I don't even have that option and then when I try a force update the dark core se completely disappears from the settings section of iCue but still shows on the home section so I am so confused with this thing now.
