This line

LoadFile.seekg(0, ios::end);

puts the file at the end of the file. You need to put it back at the start by

LoadFile.seekg(0, ios::beg);

Update

You can make the code simpler by saving the number of Devices at the top of the file. Then, you can use:

int numberOfDevices = 0;
LoadFile.read(&numberOfDevies, sizeof(int));

for (int i = 0; i < numberOfDevices; i++)

There won't be any need to get the size of the file to deduce the number of Devices.

The other alternative is the one suggested by @phyrrus9 where you keep reading the Devices until there are no more Devices to read from the file.
