Reply to CAn Anyone Help Me Out with Serato Itch?

Having a realy bizarre time wth ITCH since I got it yesterday.
I run Win XP Pro x64 so ITCH 1.1 was a must, on instal it gave me "hardware disconnected" reapeatedly (no mention of that during setup), after about 5 reinstalls, it began to tell me that my controller wasnt connected at setup.
In sheer frustration I uninstalled and found beta 1.05 which seemed to go in ok the controller works, but the sound is glitched to f*ck, pops and clicks all the way, its practically unuseable, reinstalled 1.1 got the vestax firmware update and now ITCH while works with the vci 300 the sound is terrible. I fire it up and with no tracks loaded and the faders down i get repeated clicks n pops, can anyone help me with it?

My Setup is.

Intel Core2Duo E8500 (3.16GHz O'[email protected])
Asus P5Q M/B
8GB RAM (800 MHz)
