Replication Manager Console fails after 5.4 SP4 upgrade

After upgrading to SP4 the Replication Manager Console will not load.  I have restarted the server several times and restarted the Services.  I had 2 errors during the upgrade, the first was a series of warnings saying java files were in use and I selected yes to update them with a reboot and the second was connecting to exchange which I think is due to running Exchange 2003.  I have a feeling the Java is failing.  Please help...
