Cross skipping while mixing

hi,
i have problem with Cross since version 2.0
everytime i used the program my music skips frequently while doing the mix live. i don't have that problem when i'm listening to headphone.
it only occured when i started to mix it. it sounds like the music jump or skip. i thought that problem came from the soundcard u-mix44 but when i tried to use it on traktor i don't experience that kind of problem. yesterday i tried to use the latest version 2.40 but same problem occured during my live set.
i am using asus g73 laptop with core i7 Q740 processor
8gb ram, 2x500gb hdd, ati mobility radeon hd 5870 1gb
win7 home premium 64bit.
please help!
thanks in advance
