I had the same problem when I was trying to create new projects from the template.
It turned out that my antivirus program was blocking access to the file becasue it was reported as having "a hidden extension", which when you think about it, it does.
Any one using "Hide file extensions for known file types" would see .html on the end of the file, when it is actually a .js jscript file.
Anyway, I just disabled my antivirus software, and it all worked as expected. Not the best fix, but it worked.
Hope it helps you too.
