Reply to VCI-400 Master Output stopped working!

So both my XLR and 1/4 Master outputs stopped working on me today. But luckily I have my M-Audio 4x4 sound card I can still play through for the mean while. But this is how I was able to test that it's not my cables or speakers. While in traktor I switch my sound card driver to built in and everything works then I switch it to fast track pro and still everything works. But when i try vci-400 i get nothing coming out of my speakers and the track is still playing and I still have a full feed on the mixer. Is there something I'm over looking? (which I doubt) Because I was mixing using the built in vci-400 sound card last evening for about an hour. Plus this controller only has about 10 hours play time on in so far. Can parts really crap out this soon! and does anyone know if DJTT has a warranty on this item?

Any help would be great!
is anyone else experience sound card problems yet?
