Here try this, go to control panel/ programs/ default programs/ set your default progam.
Then select the programs you want to be your default programs. This will set any and all default programs you have in your list.
Next got control panel/ hardware & sound/ autoplay
check the box at the top left that says "use auto play for all media devices". Then scroll down to bottom of the page and click the tab on bottom left "reset defaults". click it and then click save. This will reset you auto play for any media device you use. So when you insert a media device into you system you will get a popup window asking you to choose what program (application) that you want to use to open it in. There should be 4 or 5 choose from.
