Setting own store with multi vendor using the same Paypal account

I am setting store with multisite for multi vender.

Now I have setup PayPal chained gateway and having one issue.

As I am setting my own store also with multi vender and having only one PayPal account so I am using the same PayPal account for MarketPress plugin network settings and for my own store as well.

So when someone try with checkout it is giving error message "579040 - The receivers email@address.com and email@address.com can't belong to the same PayPal account"

Again I am using the same account ( and email ID ) for plugin settings any my own store. I have also tried using different email ID for the same account but none of them worked.
