Send port Certificate error : A Thumbprint should contain 40 hexadecimal digits

Hi all,

I am trying to assign a certificate on a send port. The certificate is stored in local computer-> other people.

 I have added the certificate to the cerfiticate store using a biztalk admin user.

I cannot see the certificate listed when i click on browse. So i tried to add the thumbprint directly since the certificate has a thumbprint. But this is what i am getting:

The error i am getting is A Thumbprint should contain 40 hexadecimal digits

I used the format provided by microsoft  : http://msdn.microsoft.com/en-us/library/aa578327.aspx

Please note that i tried to enter a test thumbprint value which is only numbers (40 decimal digits) and it accepted it when i clicked apply, how ever when i enter 40 digits hexadecimal values it rejects it

PLEASE HELP!
