Texture problem

Hello Unity community!

First of all, I'd like to share that this is my first time on the forums and also trying to use Unity. I used to fool around with gamemaker back in the day and lately I was really thinking about making my own game (I have so many ideas in my head) and discovered Unity!

So I started right away with using the tutorials and opened up the first one. The video asked me to import the 2D Platformer example, so I imported it right away, but... it totally looked differend than on the video. Here, I'll show you:

If I'm correct, this would be a common problem. I've followed up everything and couldn't find a solution to this. So what's wrong and is there a way how I can solve this issue?

Thanks in advance!

 

Thanks for the reply! Yes, it seems that the textures look messed up on Unity, but when I open it with another program, it looks perfectly fine.

My system isn't the best around, a laptop with 2gig of RAM, 700MB GPU and 2 cores on 1,8Ghz with DX 9.0c. Since 9 is the default setting for Unity I think that isn't the problem. Guess I'll have to work with lower resolution textures, seems no problem when I open up a simple sprite and I've tried a generic 3D sample to see if that worked alright, which was no problem at all.

Guess I'll have to study the 2D Platform example without the actual file itself.
