This might be really off topic, but I really need help.

I just started GD, and I'm paranoid and I don't want to lose my progress. The school wifi,which was terribly slow, saved my data in 2 minutes, but upon trying to save in my PC with 4 MB internet, it immediately says "Backup failed." I have no created levels, I have deleted my custom music, my saved levels. What do I do? Is this a server error or an error on my side?
