I cannot seem to get the PM module to work. I continue to get the following error:

Error: Compose Message is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Input string was not in a correct format. ---> System.FormatException: Input string was not in a correct format. at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Convert.ToInt32(String value) at DnnForge.PrivateMessages.ucCompose.SendMessage() at DnnForge.PrivateMessages.ucCompose.cmdSendMessage_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

Any ideas? This is a fresh install, so I'm not sure what could be happening.

Thanks,

Bill
