can't input audio

I have just installed Studio One (2) on my computer and have the Huxley M-49 keyboard. When I load the program in the list of functions it says 'Audio recording disabled' and in Audio setup it says 'Disabled 1' and 'Disabled 2' above the numbers 1 & 2 in little boxes.In addition on start up it says 'Failed to open Microsoft Midi Mapper'. I can't seem to record anything from my keyboard or even hear it when i press the keys. I have added it as a device. It comes up as 'Masterkey 49'.

Please help!
