"No Driver" in vst connections

I have been using cubase LE 8 for months now and today for no reason in the vst connections just appeared as: no driver.
The audio input and outputs present like “not connected” even if I create new buses. The weird part is that any other software can reproduce music and even record (audacity for instance).
One little detail that made me think is that I installed ableton live 9 early today and I think cubase stoped working properly after that, but it doesn’t make much sense to me.

Really need help, going nuts here. Thanks
