What happened to my file?

New to this forum. Installed i-Vault 2 days ago. This is what happened: I only had 1 storage file, with a password (My Yahoo). Had to re-boot he computer this morning, and when I went into my iVault…my storage file was not there at all. (Of course I tried to go into Windows search) , but, that just automatically brought me back to the desk top…which is probably good, cause no-one else would be able to get to it either.
So where did my storage disappear to?
