Reply to help with serato itch please

so, i'm a traktor guy, i'm used to the feel, the look, everything about it.
but for a party i played i had to use the ns7, great hardware, great software i enjoyed it. so i decided to get Itch on my computer so i could practice using the ns7 with all my music.

i installed the latest version of itch, installed all the drivers needed.
but when i tried to play. the cpu meter went all the way up. task manager showed cpu usage as 100%

i tried playing one of the decks, audio wouldn't work, it would play then cut out and play again, i couldn't stop it either, the ns7 became completely un responsive. i had to shut it off and manually turn off my computer because i couldnt even open task manager.

is there any way i can fix this? or is my computer just to "weak" to handle the ns7?

i have an acer aspire 5532
AMD Athlon 64 Processor TF-20 (1.6GHz)
ATI Radeon HD3200 Graphics
3GB Memory
160Gb HDD
Acer Nplify 802. 11b/g/draft-N

(sorry if that was useless info, i just typed what the sticker said on my laptop lol)
