Group Notifications not being sent

Group Notifications not being sent

I recently installed the latest service pack 6014. Since then, when requests are created, the group notifications are not being sent. I tried to uninstall the service pack, but receive an error that uninstallation is not supported. Previously the group notification was automatically sent as soon as the request was created. Is there a way to fix this or remove the service pack as this seems to happen only after the service pack was installed?
