i think i may have at some point messed with the photo gallery settings, i can use the webcam to skype but not take pictures, also when i try to use the library i can not access my old photos, and it now tells me "Photo gallery can not open this phot or video. this file format is not supported or you do not have the latest updates to photo gallery." please help! i love my computer and it has been like this for a while, its my only problem with it, and no one seems to know why its doing this, any ideas what i may have clicked at some point to make it do this? or how i can fix it? thanks in advance!
