Dumb it down for me please....

1. I checked this again, copied back the file and it worked ... I compared the file from the plugin, they are identical. I have no clue why this happens...
2. I come from that thread and i applied the prerequisite line : sudo apt-get install python-opencv
Install goes fine, but still i am not able to use rearcam. If i try to install the version 0.1.0, it fails telling me that dependencies XBMC GUI 5.3.0 isn't fulfilled. If i install the 0.1.1, it goes on, but doesn't work, when i try to execute it manually, i see a small flash on the screen and then nothing.
Isn't there a logfile for that app somewhere ?
