Problem with Virus KC Keyboard help help
 

Hi all

I just bought a Virus KC and some keys of the keyboard (2) when I pressed it fails, when i pressed with forced the sound is lower than the others.
Yesterday I disassembly the virus and clean everything but the problem still happens...I think the rubber contact keyboard set must be replaced...where I can buy this or is it an OS problems or I don´t know and this place is where someone can help me?

Thank you in advance...
