I had to be very quick in Teamviewer as I knew I would be disconnected before long. When I looked at the RA screen however I saw that the Computer ID and password had changed from what it was before. I then accessed the PC using Teamviewer and discovered that it was working perfectly. I then remotely powered off the PC and tried again with the same result. I waited a few minutes to try and access it again and this time RA was unable to connect to it remotely I got a message when I tried to connect that it couldn't find the PC or PIN was wrong (I can't remember the exact message sorry about that). This morning the remote PC seemed to have some issues (nothing to do with RA) so I decided to shut it down within Windows and RA disconnected.

I have been accessing a remote PC for some months by selecting the Computer ID which has been retained in the RA dropdown list and then typing in the password to the PC.
