I get a "Main Execution Script" error when trying to install 1.1.8 Cookies Fix.

Pls help.
I need this fix so I can surf forums and what not w/o having to keep logging back in every 2 mins. The source is Apple Daily Times and I cant install the 1.1.8 Cookie Fix and get the Main Execution Script error.

Whats causing this and how can I fix it? Thx!

 

So after some research on the net I saw I can dl Term VT100 and type in:
chown mobile /var/mobile/Library/Cookies/
chown mobile /var/mobile/Library/Cookies/Cookies.plist

I tried that and get "command not found".
Whats funny is that I never got a user name or pw prompt.

Why is this so f'n hard. I just want Safari to remember my cookies. Pls help!!!
