No Audio output when I ignored a file.

Good evening,

Last night I had to perform at a party, everything I needed for the set iv'e put into a project. Group A,till H where used.

The moment I turn on the maschine I got the notification: "SampleName.wav could not be found", so I pressed ignore and from that moment I couldn't play any samples from group C till Group H, because there was no audio. Group A&B worked fine. So I restart my maschine, and suddenly I have no audio output at all. Not even when I tried to play samples from Group A and B. The lights of my pad still were lighting up, I saw that the samples where being played, only there wasn't any audio..

I then tried to open a project from a set I did a few months ago and those samples had audio.

So when I got home the next day, I immediatly checked the project, I get the same notification about the missing sample, I press ignore like I did when I was playing my liveset, and everything worked fine? all the groups were working, I had audio except for the ignored file ofcourse, but everything else worked. so I tested if it would make a difference if I pressed Ignore file or Ignore All but apparently that doesn't make a difference.. It randomly decides if it's working or not.

The Maschine+ was in standalone mode the whole time.

Anyone else had this issue before or someone knows how to fix this or what could be the problem??

oh and I don't know if it's relevant or not but when I was doing the live set I had the audio being of the Maschine+, a drum machine(Roland) and a synthesizer send to a mixer and then from the mixer to the speakers.

when I checked at home it was checked with my headphones and also the audio output from maschine itself.

Thank you in advanced!
