Help! I just got my first linux computer, an acer aspire one and its been great for the first few weeks and today I seem to have done something that has put all of my open office files in a different location and in read only mode. The first time it happened I was able to restart and everything was in the right place. The next time i restarted, everything disappeared again. not really sure what to do next.... please help! Really important documents have gone missing!
