Nope, I have my files on a cloudy thing. I'm not sure how it works (my dad was the only one who did, really...) but I can access my files on any pc or laptop in our house. It's some kind of network thingy, I really don't know. Normally it's quite handy, but there are two major cons to it:
firstly, there's no recycle bin. If you delete something, it's gone for good. That's what happened here.
Secondly, it'll always give a warning when you execute a file from the internet. No uncheck possible. That's what happened a few posts earlier, and it's what made me not be able to test levels.
A backup should be made every week, but nobody knows how to access that backup. Besides, I think it is made on Sunday, and I did most of my work on Monday and Tuesday.
