If you get the "Need a Drive Letter" message....
That means that the computer is already connected to the cloud. Click Cancel.
Click Start->My Computer. Scroll down to where it says "Network Drives". Listed below it should show a user name that is connected to the H: drive.
If it is your name, then you are already on the Cloud.
If it is someone else's name, you need to disconnect and then re-connect. On the desktop, click the "Disconnect-to-WLWV-Cloud". That should clear the drives. Then go ahead and click "Connect-to-WLWV-Cloud" again and everything should work.
If you get the "Drives Were Not Mapped" message...
Make sure you have a good network connection.
It's possible that you mistyped your password. Try connecting again.
If it STILL doesn't work, there may be a problem with your password. You can ask the librarian or a teacher for help.
