Any chance to restore a previous build number?

I just accidentally overwritten my running code with an old version and I don’t have the new one.
Is it possible that you have the old revision somewhere?

Thanks in advance,

A lesson learned. Always make multiple copies using Notepad or Notepad++ to keep on your computer. I also don’t like the way that you can’t look at some old Inactive Models without loading them into the IDE. I realize you can do that without hitting “run” (so it doesn’t download to the imp), but it’s really inconvenient.
