Dude! Your credits are half of the whole thing! :\
And almost anything that comes from Windows Slideshow Maker counts as a slideshow, and slideshows aren't allowed. That's why your stuff keeps getting removed. Haven't you wondered why they keep removing your stuff? It's in the submission terms.
As for updating an existing submission, don't. It's a bad idea, and here's why. If you update an existing submission, you give a new submission an old score. With a new submission, you don't want to improve a score, you want it to be judged on its own merits. That's why we tell people not to upload unfinished items. Finish it and let it get the score it deserves, rather then trying to change the score an oldere version earned.
Also, play attention to details, as they affect the way people judge you and your work. Spelling and grammar are important.
Innocents: innocent people
Innocence: the state of being innocent
Secrets only has 1 c, not 2.
If you want feedback and tips, that's fine, but this isn't the best place for this. The Portal is for finished items. The Forums are what you want. Load this into your Dumping Grounds. It's the third icon from the left at the very top of the page when you're signed in. It looks like a bucket with an arrow pointing down. Once it's loaded there, copy and paste the link into the Forums (Community>Forums>whichever best suits your goals). That way, people can see it and give tips, which is what you want, but it's not in the Portal, filling your account with low scores or blams, which you don't want. ...or getting removed.
Hope that helps. :)
