Downloaded 3.7 and tried again, and I got the same error. That's the error I was getting before as well. Don't think I could have 3 bad downloads as they were all at different times. I'll just keep tinkering...it gives me something to doHaving issues flashing 3.7 as well. It says:
set_metadata_recursive: some changes failed
E: Error executing updater binary in zip etc.
TWRP 2.5.0.0
