Can anyone help with my Glitch problem.

I have just landed a two hour slot on a saturdy night radio show (www.sirenonline.co.uk) which is great BUT everytime i am in the mix i get a glitch and it pis@#s me right off. Is there any way this can be cured. I am using a VCI 100 SE with Traktor Pro i have run the Glitch fix TSI file. I am running traktor on windows 7 i turn all my software off and my wifi.
Can anyone help i dont want to be known as that chap that Djs every saturday that has the glitch lol.
Thanks for taking the time to read this and i do hope you can help.

are you using a dj techtools usb cable?i know it sounds too simple to be true but it worked for me and alot of others.as you seem to have checked the other options i would give this a go.

maybe latency??you haven't said when the glitching occurs....
