Are those two compatible?

Since we upgraded to Domino 6.5.4 we get this error in the XTNDConnect
Administration app when we test the authentication with a user :

Error Code : 2
Error message: Cannot find Username. Double check: Password for id
file (under general tab); Notes server name in the id file; Notes
server must be running.
Client version not supported by server at this time - please use newer client.

Any ideas?

We also enforced a password policy recently. We checked the
that we use to connect and changed its password. We can log on to
Notes with it fine.

Please contact me by e-mail if you can help me.
