Can no longer hear sound or see levels

Hi guys, really need some help here.
basically, my copy of cubase 5 decided overnight that it would not play audio or Midi whilst i’m using my focusrite scarlett 2i2. i’ve got university deadlines coming up next week and i need to sort this ASAP! any help much appreciated

Are you selecting the latest ASIO driver made for the 2i2 in VSTaudio?

Is the I/O setup properly in VSTconnections to the 2i2?

You could give a more thorough description of your equipment and OS etc.

Good to put all that in your signature.
