A period (or full stop) is used by windows to seperate the name from the file type you should never use one in the name because windows will think whater is after the petiod is the file type, in your case it thinks the file you have chosen is called "in" with the file type ".my" which is obviously an invalid file type. Change the periods in your file name to hyphens ( - ) or underscores ( _ ) and it will work.
