Can't Open Fritzing examples or save files

Hi,

I installed Fritzing on a System76 64 bit laptop running Ubuntu 16.04 LTS. The program starts fine but when I try to open one of the examples I get the following error:

"Unable to open '/usr/share/fritzing/sketches/core/Button.fzz': out.open(): %s

This error is for the button example but it does not seem to be able to open any files.

Also, when I try to save a file, I get an error that says "Cannot write file temp: /file path/ No such file or directory. I think these two problems may be related.

Any help would be greatly appreciated.

Best regards,

John
