Trying to install CM 13 on rooted nook tablet with MiUi - Barnes & Noble Nook Tablet

[Edit] OK so of course I figured it out within 30 minutes of posting this, after being stumped for the last day. Here is what i did if you guys are in the same pickle:
1. I downloaded an app call Root recovery tools, booted into the cm 13 recovery
2. Renamed "openrecovery-twrp-2.8.5.2-acclaim-sdcard.img" into recovery.img
3. Selected sd recovery in the cm 13 recovery- got loaded into twrp 2.8.5.2
4. Installed CM 13
[/Edit]
I rooted, installed MiUi, and resized my nook tablet partition sizes back in 2012 or 2013. Now I'd like to try another ROM but I can't seem to get anything working. I've tried several different things but always end up in my old version of CWM(v5.5.0.4) and get stuck. I need help. Here is the error log
Code:

Specifically I can't figure out out how:
1. To update CWM on my already rooted tablet?
2. To install the CM 13 ROM? It seems I may have to do it in several steps, first installing an older version of CM?
I managed to install a google play app that lets me boot into the CM 13 recovery but I can't really do anything with it.
