ok, i only compared your files with "beyond compare" and found a mistake in post_info.asp:
look for:
		strSql = strSql & ", 1 "
		strSQL = strSQL & ", 0 "
		strSQL = strSQL & ", 0 "
		strSql = strSql & ", '" & dateHolder & "'"
		if Request.Form("isevent")="1" then
			strSql = strSql & ", " & 1
			strSql = strSql & ", " & cLng(Request.Form("strMessageIcon"))
		else
			strSql = strSql & ", " & 0
			strSql = strSql & ", " & cLng(Request.Form("strMessageIcon"))
		end if		
and change to:
		strSql = strSql & ", 1 "
		strSQL = strSQL & ", 0 "
		strSQL = strSQL & ", 0 "
		strSql = strSql & ", '" & dateHolder & "'"
		strSql = strSql & ", " & cLng(Request.Form("strMessageIcon"))
		if Request.Form("isevent")="1" then
			strSql = strSql & ", " & 1
		else
			strSql = strSql & ", " & 0
		end if		
If it doesn't help the get your backup files and reinstall the mod.
