So, I'm sitting here trying to create a usb drive for unraid using the flash creator without any kind of luck. I open up the windows version of the app, select stable of version 6.6.6 then chose my usb drive and hit Write. It downloads the media then I'm presented with an error: Couldn't open C:/Users/*****/AppData/Local/Temp/unraid.bootimg.gz. Is there something obvious that I'm missing?
