 USB Firmware Tool 1.15 - Error when pushing image

I'm getting the following error when I'm pushing an image to one of my Thin Clients (Z90S7) Windows 7 embedded standard. I successfully used the USB Firmware tool to format my USB flash drive, and was able to pull an image from another Z90S7 thin client. However, when I try to push it out, I get the following error.

Error encountered during PUSH operation:

[media_validation_stage][mbr_file_could_not_be_downloaded_properly][check_your_network_connection]|Exc=215

Any ideas on how to get around this?

Thanks!
