Always freezes up on me, what am I doing wrong

I am getting extremely pissed because every time I try to use scrapebox for what it is for, after some time it freezes up on me.

I let it run overnight, and currently, it is unresponsive to anything. It still says harvesting, but clicking stop isnt doing anything, i can click on the toolbar items (but of course everything is grayed out) but it wont stop.

So once again, all my harvested links are gone because I assume I will have to force close scrapebox.

I am using private proxies, and scraping keyword+a footprint trying to get links. on my PC. dont know what the problem is.
