I tried to check the Certificate Revocation List, but it seems it’s not to be a valid one.
Will that not be supported anymore ?

Sorry my fault, We are in 2012.
So it should be valid. But the Point is when i check the Certificate we got the Message :
Warning:
The Certificate Revocation List needed to verify the signing certificate is either unavailable or it has expired.
