Just installed mavericks, erasing the hard drive and installing it as brand new; then I wanted to restore my backup from Time machine (as I always did) but an error screen appears, saying "impossible to open every backup". I'm kinda scared, I don't have other backups and I always considered time machine on Time capsule as reliable. What can I do? I tried both from the startup of the new os and inside Mavericks, from migration assistan.. please help!! I have my whole iphoto library on it..
