Problem upgrading from 4500
I installed the upgrade pack to go from 4500 to 4603, on my way to upgrading to the latest version. The update seemed to go ok, but then we were unable to log in to the web interface. At this point, I tried to use the updatemanager.sh script to uninstall the service pack, and it gives me the error "Some exception occurred during previous patch installation / uninstallation. Please contact support team." And I also get this same error if I try to install the 4603 to 4700 upgrade pack. After this, I cannot even get the PMP service to start. This is running on a Linux server.
