1st edition Naga

Hello guys. I still have my razor mouse and keyboard and headset i bought back in 2010 (with original boxes ;). Razor Naga mouse, Razor Lycosa Keyboard and Razor Megalodon Headset. I love them and won't change them, especially that they cost me almost as much as my pc back when they were released! :P I have an issue that my mouse wheel does not click anymore and wanted to re-assign it to any of the numbers on the mouse, unfortunately i downloaded the razor Synapse after doing some online research and the program does not support my mouse... Please help! Thank you
