Installing Premium Wordpress Theme?

[rey2k5]

So, no matter what I did by following the instruction, I can't seem to get any premium wordpress theme to look exactly like the demo. Themes from themeforest, yootheme etc, they will always look really different after I installed it into my blog.

Anyone knows what I did wrong or is there any trick in all these? I am so confused!

Make sure to read full doccumentation after purchasing a theme

There are tons of option in it for you to change/Activate! Just look around! read the guide!

they should provide you with a XML file, which has the original contents. Ask them (at least in Temeforest) if they can sendit to you.
