Feel very silly but changed my user name as I recently married (not shortname) and re-booted to discover virgin desktop on Macbook Pro OSX - seemed to have lost all my documents, photos and itunes, desktop etc. Asked me to recreate new Mail account - have no address book and so on - however, think it's all still there, but cannot access them. I.e. in iphotos can see my folders but viewing pane all grey and cannot access. Bought Leopard yesterday to upgrade so that I can use Time Machine - but do not want to install before I can recover and back up my data - if it's possible. How can I get back to my old system? Please help!!!
