Hello Paul,
Unfortunately, we haven't received any emails from you. Could you please resend it to support@remoteutilities.com once again?
Meanwhile, please try removing the config_4.xml file from the Remote Utilities Files folder as described in previous messages and then registering the Viewer with a new license key. You can issue a new free license key using this
Free License Key Generator. Please note, that you need to use an email address you haven't use before.
Looking forward to your reply.
