I've been working in the Web Editor for a few weeks. I've imported sketches, edited code, uploaded to my Uno and everything was working great. Last week, I experienced the "doubling up of examples" issue. A few days later that was resolved but since then, every time I try to import any sketches (including the original sketches I downloaded from Github), I get this error:
"An error occurred while importing the sketch. Please make sure the file is not corrupted."
I've tried from my Mac (10.11), PC (Windows 7 Pro SP1 64bit) , Chrome (61.0.3163.100) , Safari, all with the same results. The sketches open fine in the IDE.
Any assistance or suggestions would be appreciated.

Note1: "Import File into Sketch" works. Seems to only be zip files that have the issue.
