Hi Dawnz, Thank you for posting this issue, I was just trying to determine what went wrong which might help.
I do suspect something may have became corrupt in the Dragon user profile during an update.
You could try the Portable version, this will eliminate any Dragon user profile issues.
Note: The Portable will not effect your installed version. Portable Version
You could also create a new user profile without re-installing, but please note bookmarks, personal settings and preferences, etc will not automatically roll over to the new profile. To create a new user profile in Comodo Dragon
I recommend backing up your bookmarks to a HTML file before hand, they can then be easily imported into the new profile. Importing And Exporting Bookmarks
Of course trying any of the above is your choice.
