C64a

So today i was trying to change some numbers in trials frontier with igameguardian and i messed something up. It seems to be a problem with my particular save/uplay account. The a.n.b.a robot doesnt show anything and the game crashes 95% of the times i try to run it or download my save. Stupid as i am i never made the documents folder backup. Is there something i could do to bring my save back from lets say yesterday?

Thanks!
