Computer re-named SDHC card, now won't work

I inserted a SDHC card into a USB reader and when the file options came up, I chose to view the pics…which was fine and I looked at several.  I wanted to edit a few of them so I closed the viewer program and went to COMPUTER > EOS_DIGITAL (E; DRIVE) >  as always, 2 file options opened (DCIM and MISC) > I doubled clicked DCIM and that in turn opened the same 2 customary files (100CANON and EOSMISC) > I then double clicked the 100CANON - instead of pictures becoming available, the disk was renamed and I cannot access the pictures.  The snip of what the file name now looks like is attached…it seems that the datat is still present, I cannot access it because of the error "The specified path does not exist.  Check the path and try again"  I have also attached a snip of what this error message looks like.  I would appreciate the help.📎SDHC card label.PNG📎Error message.JPG

It's not very helpful, but I answered in your other topic here:  http://forums.whatthetech.com/index.php?showtopic=129789
