Superstar software cannot read books.

I don't know the details. It's just that the books under the superstar can only be read on this computer. If you read them on other computers, you have to apply for an offline code. Very troublesome. My permanent solution now is to virtually print a png picture in a common format and then read it with a picture reader. Not bad, no longer afraid of being out of date. It's cool. The method is what I said in Know. Look at the previous one.
