I contacted their cutomer support and he said : Try the following;
Unplug your V7 from your computer.
Use a different Keyboard and begin to re install your driver from cyborggaming.com
the install WIZARD may ask you if it is ok to un-install or overwrite the previous driver, if it does please agree to it and click on "yes to all" if it ask to overwrite any files.
If the install WIZARD then ask to restart your computer then do so
Once new driver is INSTALLED plug in your keyboard and you should be set to go.
worked for me thank god i love this keyboard so much
