First data api certificate creation error in asp.net

I have downloaded the permission file ("1909642928.pem") from the first data website, and put it into the solution folder. While trying to create a certificate file for the application from the permission file ("1909642928.pem") downloaded from first data website, I am getting an error:

The system cannot find the file specified.

CryptographicException:

at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I am getting error form the following line:

FDGGWSApiOrderService OrderService = new FDGGWSApiOrderService();

OrderService.Url = @"https://ws.merchanttest.firstdataglobalgateway.com/fdggwsapi/services/order.wsdl";
OrderService.ClientCertificates.Add(X509Certificate.CreateFromCertFile>(("xxx.pem")));

Please assist me if I have to do anything more to create certificate from the permission file.
