After only my safari didn't work anymore now i've got internet again because of firefox but now all the apple programs such as iphoto, ibooth, itunes and pages etc. stopped working! When i try to open them i get the message 'the program quit unexpectedly' (translated from dutch) I think this is because i installed an older software version over a new one, but if this is the case, how do i fix it? I if go to the apple sign and click there on software update that program shuts down too! Could anyone help me?
