If your machine is up, Apache & MySQL running, harddisks OK, it may mean that one of Officity ressource is missing. Check the following :

• the OS directory does exist and contains the files core.swf and index.php
• the Library directory exists, contains another directory OS which itself contains a file graphics_custom.swf

If these last checks are done and not solution was found, please take contact with the Nectil team.
