Default Capture Caption changed to Times New Roman - now is No font selected after Win10 upgrade

Ok, I researched for 4 days, read all your postings plus others but cannot find my situation.  I have Cp9, I created 10 simulation projects, the Default Capture Caption Style was the one selected for the clicks.  All the slides used to show Arial as the font.  I saved, published all the projects.  I checked these periodically and the Arial font was there in the project and published content.

2 weeks later, I upgrade my laptop to Win10. Before that, I made a backup of all my .cptx and .cptl files. I don't have saved styles, I use defaults.  My work uses a method of clean install, so it wiped the entire disk. I reinstalled Cp9, copied the captivate files back to the folder.  I open all of the projects and the boxes where the click was recorded, it shows the font as Times New Roman (TNR).  The Default Capture Caption Style in the Style Manager shows "No Font Selected". for Family and Style. I read that if a style is set to No Font selected, Captivate uses the first available font from some kind of list and Times New Roman is the one selected.

Now, why the project had the Default Capture Caption Style set to Arial and after the re-installation, it changes it to No Font Selected?  I go to the style manager and change it to Arial but it is not updating the captions.  They stay in TNR.  I've been doing multiple things from copying and pasting to another project to changing to another style (that works but I loose the boldface I applied) and back to Arial but I don't get the boldface font in some of the text.  In other words, if I manually change each object in the properties to Arial, it fixes the font and shows the boldfaced words.  But this is one at a time.  I can't make a global change to all the Default Capture Captions objects to put it back the way it was (Arial font).

Sorry for the long detail but I needed to give you the entire picture and since you provide a lot of good recommendations and fixes and wanted to be comprehensive.  Have you seen this behavior before?  Is there a file that I can open and change that attribute to Arial? Thanks for any help.  -- Miguel
