That’'s probably because the XMPP Fed cert. is AES encrypted.
You need to manually decrypt the private key before the import tool can import it.
If you have access to a Linux machine, you can decrypt it there, otherwise you need to somehow install openssl on windows to decrypt your private key.
When you open the undocumented page that contains the import tool, it should give you some indication of this.
Mine says: "Use the form below to import a private key and certificate that was provided by a Certificate Authority. At this moment private keys encrypted with an AES algorithm cannot be imported. You will need to decrypt them before importing them. However, DES encrypted keys can be safely imported. To decrypt a private key file execute the following command: “openssl rsa -in ssl.key -out decryptedssl.key”.
