Trying new config.plist, gets AppleKeyStore failed

I just bought a used EliteBook 2570p. I've worked with similar Elitebooks before but wasnt versed as well with Clover back then.

I was able to install it using a USB key used to install OS X to my Lenovo P580 laptop, used defaults all the way and it installed perfectly. I was messing around and deleted the original config.plist. So I used Clover Configurator to generate a new one using "Generate Config. This put a config-generated.plist file on the desktop, which I then moved to the Clover older on the EFI drive and renamed to config.plist. Everything looked fine, even after making a few edits. But every time i attempt to boot from the hard drive i get the following:

Unexpected session: 100000 uld: -1 requested by: 32

AppleKeyStore: operation failed (pid: 32 sel: 7 ret: e00002c2 '-536870206', -1, 100000)

At that point it delays, then times out and goes to a black screen. The edits I made were by generating another SMBIOS file for MacBookPro5,2; setting the GUI to 1366x768 resolution, and hitting calculate on the Root Variables page and saving the file

Now easily I can go use TonyMac's tools as there's a special set of files for this, but I'd prefer to use the generic stuff and learn more along the way. The laptop is for a friend of mine so I can stall on it. I'll do more research on Google but am hoping to find ways to fix it here. Is it an easier fix in Clover Configurator, or is it faster just to reinstall and start over? (12 minutes w/ an SSD)

Edit: I can also get back in by booting with the USB key.
