backup to this pc issues

hi there,

I have had to make several starts with this software :-) as I udnerstood the cacheing principle wrong, so I ended up with too much space for cache and nothing left...

My solution was to wipe the stick and reinstall but now when I select: backup to this pc and select my sticks name it says: "backup name already exists, try again" - of course it already exists...

what to do?

I could manually delete the backup as there is nothing backup up yet but I would expect to be asked if I want to overwrite that backup or restore it - seems to be the more appropiate choice - at least to me. what do you think about this?
