HELP! Can't re-image Classmate Laptop

Long story short, my team's Classmate is unusable. We used my personal laptop during the build season but at Regionals it would not connect to the field, so I had to borrow the regionals' Classmate.
So for St. Louis, we borrowed another Classmate from a disbanded team. I'm currently trying to reimage it to this year's image since the team disbanded a couple years ago.



I'm following the How-To, but after clicking Prepare Drive (step 4, at the top of page 7 in the link above), it runs the command prompt, Extracts everything, the command prompt minimizes, but I never get the confirmation window saying that everything copied over successfully. It took about 15 minutes for the Command Prompt to close itself, but it's been another half hour or so and it still looks like the attached picture

Note that the red text at the bottom still says its in progress, but in the how-to, it doesn't show in-progress red text like that after the process is finished. The inserted USB key is also no longer flashing. I'm thoroughly confused
