In the first case "As i said go to the VMs folder location in explorer and check how many virtual hard disks you see (and their sizes )"

I could go to the VM folder location and see the virtual hard disks.

There are two files of 20 GB each. Please see screenshot below.

In the second,"Check the virtual machines NIC is not disabled and also the virtual network it is connected to."

I could see the NICs are enabled and still the link was not coming up.Screenshot below.

Please suggest.
