Sounds like a problem I had a while back

Recovery re-installs the currently installed version. Also, using ADB I can see the new cm-nightly zip file in /storage/sdcard1/Download.
I don't see TWRP during the reboot. Should I??
I also don't get an option to select a new image to install. Should I?
I also tried copying the cm-nightly zip file to the /emmc directory and that doesn't seem to make any difference.
You may be having partition problems. I have had either lost the ability to install new nightlies or the ability to backup. Read the instructions through completely first. Get the info together and then start.
If you have a backup App like titanium backup, backup all files and data before anything else. Also if you can, do a backup in recovery before doing the following.

I set up a 2Gb sd bootable card to run these from using the CWM recovery (If you need help check eyeballer's link below).
I put the partition repair files on it. Also the 1.4.3 Stock rom, the TWRP open recovery. zip 188.8.131.52 (http://forum.xda-developers.com/show...&postcount=129
), and the latest Rom you want to install and Gapps.
After following leapinlar's instructions including installing the 1.4.3 Stock rom (fixes other possible problems), then follow eyeballer's install for the Rom, Gapps and recovery here (http://forum.xda-developers.com/show...+to+nook+color
After booting and doing the initial CM setup return to recovery and VERY IMPORTANT ***restore only the data
*** Not boot or system from your latest backup. This should get you back up and running. If you have a backup like Titanium restore "newer versions of apps" if you had to use an older recovery backup. Once you have everything set reboot into recovery and do another backup for safeties sake.
Including my wife's Nook I have four units and have needed to do this 4 or 5 times. Takes a little time but has always worked great. I keep the card available and update the Rom, Gapps or whatever else needs changing.
This link also contains a lot of helpful info. I have all these bookmarked on both my PC and Nook.
