Ubuntu :: Shar File, But Karmic Says That It Is A Shell Script?

I downloaded the demo of Penumbra Overture, it is a sh file (113Mb). I can't open the file.In a terminal I ran chmod +x PenumbraOvertureDemo-2553sh and then sudo./PenumbraOvertureDemo-2553sh and I get an error "./PenumbraOvertureDemo-2553sh: 2:Syntax error: "(" unexpected" . The quotation marks are my own. Is the file corrupted?ne of my lugmates thinks it might be a shar file, but Karmic says that it is a shell script.Another friend says that it is too large to be a shell script. Here is the code:

johnjohn-laptop:~$ cd /home/john/00
johnjohn-laptop:~/00$ chmod +x PenumbraOvertureDemo-2553sh
johnjohn-laptop:~/00$ sudo ./PenumbraOvertureDemo-2553sh

[code]....
