After 2-3 weeks, frustrated trying to find answer. I can make PayPal Express to run with my website.
Here's my setting

 /API Access


go to 
NVP/SOAP API integration

create then Get the API Signature - API username, Pw and Signature

Go back to your website
fill out the 3 API data in  Admin / PayPal / Credentials

That's it.

Now you can try it in Sandbox mode.
First goto http://developer.paypal.com
Create Seller acct. , Buyer acct. for sandbox
Then go to http://sandbox.paypal.com
Get the 3API data from Sandbox Seller acct.
Make sure that  all the Seller, Buyer and the Shipping address in your website are all in the same countries.

if it works then you can go Live.
