I'm sorry to hear about the crash, and I wish I could help. Unf'ly, I'm not that computer literate.

I can pass on one observation from expereience. If you want people to volunteer their help, then set up a situation where people work first, then party or have dinner together. If you could top that off with the chance to make music, so much the better.

In my experience, doing good works all alone gets old really fast.
