no problem, thanks anyway. i might give it to end of night before contemplating the wipe/upgrade path.
what is best way to migrate over once i make sure everything backed up?
do i just follow the regular install instructions under the 'installation guide'?
if i've got a mac air that i want to also eventually upgrade, will this 'use up' my version or can i install on as many computers as i want? i assume the latter but want to confirm.
