i had halo wars downloaded once upon a time on my hardrive.
i had to delete it to save some room, now i just recently started downloading it to my flashdrive, and my internet went out
now i cant get it to download to my flashdrive, it only wants to save it to my hardrive!!!!! why!!?!?!?!

Idk try using a different usb port or a different flash drive

go to your hard drive, delete old file and redownload.
