Problem With 2d platform tutorial

Hello everyone, im new to unity and i have a few problems with the 2 tutorials, actually the assets and its really getting on my nerves :?.
When for example with the 2D platformer when i try to load the 2d platformer scene (thats supposed to be playable), i just see the main camera, a few sounds and a directional light, i dont see any, skyboxes, characters etc. although when i select for example the platforms in the hierachy view and press f, i see green outlines of platforms and nothing else. and when i press play i just see blue. sorry if there is a real simple answer im quite new to unity.
thanks in advance,

P.s. I added a pic to show what it looks like when i double click the 2d platformer scene. (the same thing happens with the fps tut when i try to use the weapon model or anything else)

P.p.s. im running windows vista 32-bit sp1 with 3gb ram and intel intergrated video card

Sounds like you’re not importing things correctly. The scene knows what it needs but can’t find them, hence your errors. Check you’ve setup the project correctly and try again, loading the scene file is only part of it, if you’re not using the same project, or haven’t imported the assets correctly, the scenes can’t find what they need.

well ok, this is what i do to import files, tell me if im doing anything wrong:
I unzip the archive into a blank directory (i have a folder for the project called 2d platformer project). and then in unity i go to open project, and then i go to the directory and choose select project. then after that i double click on the scene file and then that just appears.

im pretty sure something went wrong in the importing cause for like the island demo there are no problems whatsoever but only things i needed to extract have had problems so far
