Hi Tony, I removed all the fonts listed as problem fonts by FontDoctor but it did not work. Within FontExplorer none of the older Postscript fonts were active, I don't really use them, but they were still in the library as I did not have any reason to remove them before encountering the problem. However, it seems that just having them listed in FontExplorer, even when deactivated was causing the problem to happen, and it was only by removing them completely into the trash bin that the problem was rectified.
I shall look into FontAgent following your recommendation, I guess a back up makes sense should FontExplorer give me any problems. By the way the support team did respond to my email with the following message below. It's nice to know they care, although the font creating the problem was not a version of a system font as they suggest. I have not yet shared my findings with them yet.

Hello,
It is probably a conflict with some old fonts (mostly PostScript Type1 fonts) you imported to FontExplorer X Pro with system fonts (due to same post script name). So please find out which font is used in your Emails/Website. And search for old Helvetica, Arial, Neue Helvetica, Verdana... PostScript fonts (which are not a system fonts) and remove them to solve conflict with system font.
Please enable "Conflicts" view option in source pane (/View/Configure Source List/). Click on "Conflicts" icon (below system fonts), use Conflicts: "Same PostScript name with multiple activation".
