I just bought a WIndows 2003 Server with Plesk 8.3 preloaded on it from Server beach. I went ahead and upgraded to Plesk 8.4 and then installed Smartermail (alongside MailEnable) in the hopes to switch to it. However, when I try to switch over to it - I get the error: Error: Set component parameters failed: Some fields are empty or contain an improper value. Anyone have any idea what this could be? I tried completely removing MailEnable and all associated sites/apps in IIS for it but still no luck. I'm guessing there is still data somewhere it is unable to touch.
