Thanks for the concern. My pc is fixed, thank the otaku god.
I was using an outdated graphics driver for AMD. X300/X550/X1050 series. My screen freeze, or BSOD without warning. Thank goodness there was an update at AMD's website. Problem fixed.
Oh, and I mean by 400 ticket - it's sometimes like that here when there's a special guest in an anime convention. If there's no high profile guest or band.. then the ticket to enter can be only 100 pesos, or even free. ",)
450-500 peso can be too much for a book in my opinion. I know cosplayers who don't enter and just pose for pics outside, because they can't afford the 400 ticket. Well, you can still try, who knows some people might like your book. Though I would suggest decreasing the price to about 100 pesos, if that's possible.
