Tablet [Q]upgrading Nook HD from CM 10.1.3 to nightly

So recently got cyanogenmod installed on my nook HD (running 10.1.3 right now) and I want to update it to the nighty CM which is currently cm-11-20140115, when i go to install the update it reboots and I get this



What I used to root it are these files
NookHD-bootable-CWM-6027-for-emmc-stock-4GB-rev3-(02.03.13)
gapps-jb-20130812-signed

Do I have to update the bootloader? thats the only thing I could think of.
thanks
