Your profile shows a 60 series humidifier but your machine doesn't match your humidifier choice.
The 60 series humidifier only works on the PR S1 Auto CPAP 60 series and not the machine you have chosen.
If you do have the 60 series humidifier then you need to change your machine choice in your profile because I know it won't work with the other machine.
If you have chosen the wrong humidifier and do have the model 550 machine then you need to change the humidifier in your equipment to simple the PR system one heated humidifier.
This would be the 60 series APAPhttp://www.cpap.com/productpage/pr-system-one-60-series-auto-cpap-heated-tube.html
or the prior model which has a much lighter grey face plate almost silverhttp://www.cpap.com/cpap-machine/respironics-pr-system-one-remstar-auto-cpap-flex.html
So you need to make your equipment match and be sure which you have to avoid confusing us
Right now the Encore software (Basic or Pro 2.
is the only software that will work with the new 60 series models model 560. SleepyHead is not yet compatible.
If you do have the older model with the silver face plate...model 550 then you can use SleepyHead and any Encore software.
Model numbers are found on little silver stickers on the bottom of the machine usually with the letters DS in front of it but not always.
