SSL LMC-1: anyone using this? Mine's stopped being found...

Not sure if it’s Win 10 1607 or Cubase 8.5 or something else but my SSL LMC-1 suddenly can’t be found. In fact, it’s looking like Win10 because even SX3 can’t run it. I’d be gutted to lose this so has anyone else had the same problem and found a way round it?

Cheers,
C
