Hi hardasmum,
I experiment the same problem with N2O on Cubase 7, 7.5, and then PRO 8, all in 64Bits (I feared it's the problem). It's the same problem on Live8_64Bits, Vegas PRO 13_64Bits.
So, I suspect the authorization *.reg file target only 32Bits version. To be sure, I reinstalled 32Bits N2O version, then run Athaurizer. After launching Band In A Box (the last and only 32Bits audio software on my PC), I just saw that is the same issue. :-(...
Please!!! Help me!!!
