HELP no stock file!!

[Craneguy5522]

I have H&S mini max with kem tunes loaded on my 6.4. Tried to return it to stock and it says error stock file missing. The only thing i can figure is that it got deleted when i updated everything. Wont let me return with kem or h&s. I am not that computer savvy, so it was probably my fault. Does anyone have any idea about how to get a stock file??? I do have a stock file saved from spartan for a backup when it was on the truck but dont know if i can use it or not.
any help is highly appreciated.
