Found RSA certificate that is not valid for the server domain

Every time I try to install an SSL certificate itsays “Found RSA certificate that is not valid for the serverdomain.”

I have tried to import my SSL, I have tried tosign a generated SSL, and I have tried to request a new SSL using thecertificate signing request. I have also tried using KeyStore but itsays the file is corrupted.

I am using a valid wildcard SSL.

The only thing I can see is that when I add my SSLit is always two RSA certificates, rather than one RSA and one DSA.However I am unable to find how to convert one of my RSA to a DSA (ifthat makes sense, SSL is not my strong point).
