I'm sorry if this doesn't fit in this forum, but whenever I try to "Engage" it stops working and doesn't respond staying on that page, not allowing me to do a thing. Does anyone know why? My computer occasionally says "Low-memory" could that be it?
That's critically low for a Windows system, and a few patches of this game could fill what you have remaining. Try uninstalling un-used programs, getting rid of large videos, and clean out all the various caches (get a computer friend to help you if you don't know how). It may be time to get a larger hard disk if you can't free up at least 50GB.
Also, don't bump (add comments asking for help without new details, etc.) more than once a day, it's considered somewhat rude depending on the forum.
