Couldn't save as PNG in PE 19 [Duplicate. Locked.]

Couldlnt' save my .png file as a png file or mabye it did save it, but the asterisk was still there as if it hadn't been saved, so I Googled around and found this 'save as web' workaround but that of course changed the res to 72. (It was at 300.) Then I finally Xed out of the screen and when I did it asked me yet again if I wanted to save it. I did and it saved.

All I can think of is I converted and .eps to .svg in Zamzar converter. https://www.zamzar.com/ Maybe that did it?

Any suggestions? Thanks.
