[Trial version "save" and "save as" not working]

I, too am using the trial version.

 

Just spent over an hour editing a photo watching youtube video.  Can't find save or save as, so I found this thread searching for answers.  Was relieved to see here there is a File > Export option.  However, it is not available either.

 

How can I save it either as your special format, or at least a jpg or tiff?  also, where do you set the dpi for a file?

 

Thanks,
