For a few weeks now i have been trying to fix Jackle's MA5C tags (like the bitmaps, sounds, and the ammo counter). But whatever i try to fix it doesn't work

That's what tutorials are for. They help you know how to do things. Just click the "Halo CE Maps" button, above, click in the search text field, type in "tutorial "+whatever you're trying to fix (eg: bitmaps, hud, or sprites, for the ammo counter), and click the Search button

thats the problem, there are no tutorials for that sort of thing. I'll keep experimenting with it, and if all else fails, ill call Jackle an Epic failing noob

have you considered, not using it if you cant fix it?

it took you over a few weeks and you still havn't figured it out... More than an hour for a simple tag is pathetic.
