Thanks for all the suggestions. I have solved the problem.
All my TT files for 2013-14 were saved on my back up drives, carbonite, and cdrom I create for additional security. ALL showed my TT files with the correct .tax2013 extension but with adobe acrobat as the file type. How this happened is mystery to me. Other years are just fine.
So took one of the 2013 TT files, right clicked to get "properties", and could see that the file was "linked" or associated with Adobe Acrobat. I clicked on "change" and associated it with my TT 2013 application.
Now it loads in to the 2013 TT app. Tried the same fix for my 2014 TT files. Now they load in that year's TT app.
FYI before fixing it, I did try to change the .tax2013 file extension to .pdf. It would not load in adobe or TT software. I do save all tax returns to pdf files as well. FYI I could find any way to load pdf TT files into the app. TT says this can be done, but it did not work for me.
