Escalation Email Rules & Email Profiles on LINUX

I've recently installed OpManager 5.6 on a Red Hat 9.0 server. I've encountered issues with Notifications & Escalations. I've created several Email Profile for Notifications but when I go back to edit any one of them, the screen just says "Error!" instead of showing the form to edit a profile. ALso when I attempt to edit an Alarm Escalation Rule, the browser reports that runtime error has occurred in line 1539 with the error: Object expected. If I change the To Email Address and click Save then go back, not only does the error reoccur but the To Email Address has not been saved, it's still the email address from Mail Server Settings. If I change the email address in Mail Server Settings, then the address changes in the Alarm Escalation RUle but I want different rules to email different addresses. Is there a way to fix these errors or edit a conf file somewhere to change email addresses?

Also I thought I'd go into the client on the server's console and ran ./StartOpManagerClient.sh but I get a message that the display variable has not been set, when I enter localhost:0.0, it tells me that it can't connect to X11 window server. I do have KDE installed. Is there a way around this?
