Can someone pls explain the "Main Execution Script" error to me?

[STC]

Ok I asked about this error w/ "iBlackJack" and the "1.1.4 Cookie Fix". No one seems to know how to fix the apps. I've since given up on these 2 and all I want to know is what this error means??? I have only gotten this error w/ these 2 apps, and every other app works fine.

What does this error mean??

C'mon someone must know. I'm not the only one whos has seen this error.
