Reply to Quality VCI-400 and Service from DJ Techtools?

I have a sad problem. After only a few events (3!!), my VCI-400 EGE shows a problem!
It is one of the loop knobs some is not always working. The push function is only working when I push it down and forward a bit. After receiving the unit I fitted into my case and there it has been since. And because of the fact I hardly used that button it must been a "glitching" error which was there from the beginning.
