Strange, I have try it and seem to work correctly. Please delete the IMDB(Complete) script (it's the TXT file in the subfolder "Scripts"), because I think it's corrupted, then use the liveupdate to download it again.
In the process of doing that and will inform you if I get an error again. I suspect that you are correct that it may be corrupted and if I have any issues I will post them. You can mark this solved :-)
