Don't know what happened -- tried to save HTML content several times, and can't. Tried repair, installed another version, nothing helped.
Thanks
Update: I think the problem is with USB stick. When I copied the file to desktop it worked. Anyway, I think my USB stick needs to be replaced. Curious what could have happened. I reformatted it because it didn't work with Apple then reformatted back, and now there are those probelms.
