Reply to Broken right channel fader (upfader)

I was just in the middle of mixing yesterday with my Vestax VCI-100 (with which I haven't had any problems) and all of the sudden the right channel fader (upfader) stopped working and the left upfader moved both at the same time. Thinking it might be a problem with traktor pro or my software, I shut off my computer and turned it back on as well as restarting the VCI-100 and the right upfader still didn't work and the left one moved both. I even tried it in Virtual DJ and nothing. Furthermore, moving the right upfader doesn't even send any MIDI information. Is this a common issue because I can't find anything on it? I don't know what to do because I ordered it through Amazon.com about 5 months ago so I don't believe I'm covered by any warranty or anything. Help would very much be appreciated. Thank you.
