Hi Ussa Gi,
I am not sure I understand all of your story. But I think I got, that you had a couple of AP files that was corrupted because your harddrive had errors. I am so sorry to hear this. Always devastating when you have done great work and it is ruined and nothing to do about it. As an artist you are sometimes confronted with the “pleasures” of computers like you just did. 🙁
I always think like this, when something similar has happened to me: It seems to often turn out better when you have to redo something – and at least it is always faster to do it the second time. Hand drawn animation is all about drawing and drawing – training your skills. This is training! 😉
Thanks for your sad story. I hope you end up with great results no matter if you start over or you go on to something else 😉 Good luck!
Best,
Niels
