Software simply does not work

No idea how to work with this app. Starting it leaves me with a blank screen. No idea how to address it from my computer or how to push files to my iphone. The "i" icon does not react. The "HardDrive support" link leads to the homepage full of ads but without any manual or quickstart whatsoever. Deleted it from my iPhone again. Pity for the money.
