PLEASE HELP ME! I've lost a livery

[DS13_supergt]

Soooooo, i've been working for some days to modify livery created by someone else, (Honda nsx gt500 2016) today i log in and all the decals on the livery disapperead, the only strange thing that i've done is trying to see how the type b spoiler looked without even applying it, i'm so frustrated, i've spent a LOT of hours on it and now it's gone just before being finished.

Is there a way to recover the livery?
