addon fails to work - documentary.net reports 'script failed: addon.py'

Hi I'm newbie here.

Has used XBMC (Windows, Eden 11) for quite long. But recently documentary.net (from xbmc addon family) became invalid.

But after reinstalling (recent version 1.1.1), it cannot be run.

The reported error was 'script failed!: addon.py'. I tried the same documentary.net addon on other Windows 7 pc with the same XBMC eden 11 with no problem.

I tried to enabled debug log, but found no apparant clue.

I'll be thankful if anyone here can give any advice.

Many thanks!
