unmenu won't start, but prints no errors

Along with my flaky booting problems (see other post), I can't get unmenu to run now.

I go to /boot/unmenu and run "uu" or "./uu".  In either case, I get no output from the script, but it doesn't run - I can't get to the unmenu web page and "ps -ef | grep uu" returns just the "grep uu". 

This was working before, but I can't get it working now to save my life.

I tried "bash --verbose uu" to see if that would give me some help.  Seems like maybe it was dying at the point where it was looking for the awk script, which IS there.  The output is below.

root@Tower:/boot/unmenu# bash --verbose uu
#!/bin/bash
# version 1.1 - added remount of flash drive to eliminate access time update

# version 1.2 - now handles restart of unMENU on user-signal
