old iPod mini can't be recognized after formatting, and iTunes 'Apple Mobile Device Driver not found.'

My roommate gave me an old iPod Mini a few days ago. It was working fine 'til I plugged it into my computer and it asked me to format it. I did, and now it cannot be recognized by iTunes or my computer. My computer views it as a "removable disk" which cannot be accessed. In devices, it is listed as an Apple iPod though, so I'm hoping not all is lost. I have tried many quick fixes I've read on internet (including changing disk letter) but to no avail. I have reinstalled the new iTunes and now that is telling me it has not installed properly, and when I ran diagnostics, it reads that the Apple Mobile Device Driver not found. I will copy & paste all the info from the diagnostic run below, and if anybody can help me with my new (old) iPod, I'd be everly greatful!

Thanks!!
