I didn't get any answers to this, but I was able to figure out a few things.
For my problem, I didn't have ALL of the parcel fabric layers set to editable. I had a few of the layers to not editable because I didn't want those adjusted by the tool. After setting every layer in the parcel fabric as editable, I had less error messages.
This also applies to regular layers. Any feature that is within the area of being aligned needs to be editable.
For any errors after setting everything to editable, I still have no idea. Reopening the map project file makes it work sometimes.
