I've kept every File you ever sent me, and, though I don't have any of the active Projects, I do have many (but certainly not all) of your finished Works; let me know if you ever need any of them.
As far as the Loss goes, I'm not sure what to say, or really if there's anything that can be said. Such a Loss is, in some Ways, irreparable, but you must push yourself to recover from it. I know you can recreate Music by Ear, and, though it sounds lengthy and painful, that may well be what comes next for you.
In Future, Dropbox is, I find the most reliable Means of File-Keeping (simply uploading whatever it is you want to store to it works best, I think, even if it makes redundant Copies of Things at times).

That's terrible! D: It must be so de-motivating to lost all your hard work. T_T Don't give up, though! It's a fresh start, is all. I remember some guy zero-bombed all my submissions right before I uploaded Embedded, my most popular song to date. ;)

At least with those, you have all the stems... I have nothing to start from. Fresh starts are NOT good when you've got works in progress. I was planning that Sacred Moon cover and a few other things, and now everything's gone.
