Paypal pro UK module display error

[sheik2shop]

Hi all,

i am using VM 1.1.5 stable version. I have integrated Paypal pro UK payment module.

When i make a order using paypal pro, it shows the error like "1. Invalid Vendor Account. and 2. Error in processing payment(paypal pro_UK) ". 

I gave the merchant login name and vendor id(both are same) in the config section in admin. and also i gave the password for that.

Or Is there any problem in vendor account?
Please advise me how to get vendor account id and password from paypal.

Is there any problem in my payment module? Please send Paypal pro UK module free download link if any.

It's urgent.
