Hi Julian,
I'm Christine, a Windows user like you. I'll do my best to help you. I can see here that your DataStick Pro is not being recognized by your computer.
May I know when did the issue start? Is there any changes made?
Please send the make and model of your device. (Please press Windows key + R and type msinfo32 and hit enter, look for system model)
May I know if you can use other flashdrive on your computer?
Have you tried to use your DataStick Pro to other computer? Is it working?
Will wait for your response. I'm just here.
Thank you,
Christine L
