I thought I would make an account and reply. Mine stopped working as well, the CUE software is rather difficult to work with. The solution that worked for my Scimitar side buttons suddenly not responding after a windows update and computer reboot was too close the application after i had mapped the keys and saved that hardware profile to the device. After that the mouse worked as intended. I did however wipe the hardware profiles on the device and force updated the firmware on the mouse as well as re-map all the keys i had bound before figuring out that once I closed the program the mouse worked. Not sure if this contributed or not. This is confusing because when i bought the mouse a month ago, I had to have the program open in order for the mouse to work properly. Theres also an issue with software profiles, seems to want to default to just one and impossible to have more than one software profile for devices. (If you own multiple corsair hardware.) I hope this helps someone, I just stumbled onto it accidentally while trying to reboot the program.
