Reply to S4 major audio dropouts and USB errors since Traktor 2 update?

Hey guys

Well after singing the praises of the S4 to everyone and their Mums since I got it I've had my first bad experience with it.

After months of gigging with no problems I played out toevening and had a complete evening mare with dropouts every 4-5 seconds. It was completely unusable and I had to give up on the set, loosing a fair bit of money and looking like a complete idiot as I had a crowd around me checking out the S4. I had a look at the S4 diagnostics and it was showing LOADS of USB Data errors. System performance was fine with a few peaks but nothing major.

Not sure what might have happened as it has been flawless so far, the only thing is I updated to Traktor 2 a few days ago (which I haven't really tested properly, presuming that if anything it would be even more stable, my own fault there).

If anyone has any ideas on this it would be appreciated, I'm pretty gutted right now. I'm running a C2D 2.5ghz HP dv2899ea laptop with 4gb ram and Windows 7 64bit. Like I said nothing has changed except the new copy of Traktor.

I've actually got another gig tomorrow evening so really need to get this sorted before then. I'm in the process of rolling back to the old S4 software and I'll check out the beta driver for the S4 now. Out of interest did Traktor 2 come with a new driver for the S4?

Cheers for any help
