Permission to create or delete the output file

I have been using Premiere Elements 10 for several years.  Suddenly last week I received an error message while trying to render a project to a file.  The message says, "You do not have permission to create or delete the output file."  Never seen this before.  It will only allow me to render to Adobe Flash, not mpeg, avi or windows.  I have the software on two different computers, one on Windows 7 and one on Windows 10.  Both are showing the same error.  Has something changed with my license?
