File gets corrupted every time i export

I have tried to export a video that I have but it wont let me. The file gets corrupted everytime and I cannot use it for anything. I do not understand why this keeps happening and I had to use all my free renders for it. So i had to buy premiere rush to try again. But it is still not working. Im downloading on a pc, windows 10. 

Really wanna get it rendered properly so I can post it. Spent a lot of time on it
