So originally, I didn't know that 64 GB SD cards could not run the first boot for ML, so I borrowed my friend's SD card which is 32 GB. After installing ML on that SD Card, the installation ended up working fine for the 32 GB. However, when I tried with my 64 GB card again, it still had the Update File Cannot Be Found error.
