Q: My MIDI has stop working! No response from Midi Monitor

Hello guys! I rarely create a discussion in the community because I rarely have a problem or a problem taht cant be solved online, but this one is really messing with my patience and my DIY powers!

So Ive been using for a few months a Serato DJ Controller from Reloop (Terminal Mix 4) for the Serato DJ application, never had an issue, perfect plug and play controller. But a few weeks ago my HD started bothering and I replace it for a HDD which made Mavericks work faster and smoother. All my applications working flowless as I carbon copy my HD and transfer it without an issue,

A few days back I had to paly a set and the device was no longer recognizable. I check everything I could find online, including replcing firmware and monitoring the MIDI... and the result was that the device is fine as it works great on a second laptop identical to the one I have, so the problem was the MIDI of the laptop I use for shows. MidiMonitor shows me no signal whatsoever coming from the device.

Any ideas that could help me get the MIDI back in serv ice?

Thanks in advance for all your help my friends!!
