Hello Colin,
Thank you for the clarification.
Sorry for the late reply, my message seems to not to appear somehow. However, I have forwarded all the information you provided to the development team and we're currently investigating into it.
Also, it would be very helpful if you could send us your address book file. By default, the general address book file is stored in this location: C:\Users\<user>\AppData\Roaming\Remote Utilities Files\connections_4.xml. You can send it to support@remoteutilities.com if it's convenient for you. Of course, you will need to change the credentials afterward for security reasons.
Looking forward to your reply.
