who can help me ? what is the problem?
For a PSoC3 (CY8C3xxx) or PSoC5 (CY8C5xxx) you have to use PSoC Creator:http://www.cypress.com/?id=2494
PSoC Designer only supports PSoC1 (CY8C2xxxx).
Once you have donwloaded and installed PSoC Creator, you can find many useful collateral like Example projects, Application notes, KB articles videos etc in the below link.
And this Getting Started video may also help.
