Fate/Extra

[Joshuam303]

I need help with this game,

*SPOILERS*
I've been playing through it on my computer and after picking the servant I wanted and re-awakening in the hospital after passing out, the game won't stop freezing.
When archer is questioning my character about if he knows about the war, if i choose the "Holy grail war?" choice then it freezes, and if i choose the yes route it freezes can anyone try help me ? i was really looking forward to completing this .

Also i am having the no background sound issue, so will that android sound program thing still help get the sound back?

*EDIT* I've been managing to get through a bit with just saving the state when it crashes, then loading it, and it goes past the crashed bit, but i've had to do this at nearly every chat so far and it's just putting me off the game :/
