Windows 7 Trouble using "Open With"

Hi - I am trying to use the "Open With" option in order to open a photo in Photoshop Elements 11. However, I'm having trouble. Just the program will open but it won't automatically open the photo (I can open photos from within the program by going to File - Open just fine). In a previous version of this program it worked just fine using "Open With" to open a photo. One time I put a photo on my desktop and used "Open With" and it worked just fine with version 11 of the program. However, I can't seem to get it to open from that location now or from any other locations using "Open With". I think the problem may be that the item on the "Open With" list is pointing to the wrong thing so I try to select "Choose Default Program" and select the correct program by browsing there (the file I need to use is called PhotoshopElementsEditor.exe). However, once I click on this file that is supposed to be used to open the photo and click open, the file doesn't show up in the Open With dialogue box. It's not even there. The only thing there is the wrong link despite the fact that I clicked on the right link. I checked and I do have full permissions for this file with read/write capabilities. Any help would be ***greatly***appreciated. Thanks.
