Occasionally if a file sharing system has not been connected to in some time the 'token' will expire
The token is the key supplied by your file sharing system used to identify Buildlogic and allow Buildlogic to save files
When this token expires it needs to be reset from support
Below is an example of the error you may see which points to an expired token:
If you get an error similar to this, contact support to reset your token
Once the token has been reset you will need to reconnect your file sharing software
Make sure you use your file sharing Administrator logon not just a standard user
To do this you will have to navigate to the System drop down
System > Settings - File System Tab
Click to reconnect and ensure you log in with the File sharing Administrator Logon
