MS Photo Editor Can’t determine type Error

I am using IrfanView and MS Photo Editor to open jpg files but I encountered some problem with it. The message I get when using MS Photo Editor states that "Can't determine type". I obviously could not open the file. I have tried to look over in the net but I couldn’t find any comprehensive answer and it didn’t work. Could the header information (EXIF? info) have been corrupted? And if it is what should I do next? I hope this would be the place that I could get the help I want. Thank you in advance!
