Reversers Not Deploying + CAS warning (and nose wheel door won't close)

[leinsters]

Hi guys - last night upon landing at KRNO my reversers didn't deploy despite them being turned on. A message in yellow appeared on the CAS saying they are not working (can't remember the exact wording). Any ideas? 

Also, as I was shutting down I got a warning in red regarding the nose wheel door. I was not able to close it inside or out using the little switch inside the APU door. 

Any advice would be greatly appreciated. 

Cheers, 
Thanks

Reversers: did you have the 14th stage bleed on - that's the thing that usually gets forgotten so the reversers are not able to be powered.

Nose Door: needs hydraulic power to close. Did you maybe have it open, then switch off the hydraulics?
