Recorded audio too early in relation to backing track

Hello everyone. I bought my Pro Tools a few months ago and I'm having more problems than joy with them:) I have tried to fix those two problems but just can do it on my own, I'm probably doing something incredibly stupid, maybe someone will spot it. I have a PC with Windows 7 and Pro Tools on MBOX 2 Mini. Monitor cables connected to monitors, 48V button on, mic cable then the headphones cable. My main setup is that I record vocals into a session with an mp3 backing track. When i first installed the system it was working fine and at some point it started to do weird thing. I record in headphones with the backing track in them and the track on which i record to be muted (otherwise i get my voice back with a delay) and with muted track i still get my voice back into the headphones (don't know if that should be the case to be honest) but without latency. the backing track is not armed for recording. I record the new track and then when i listen, the RECORDED track is slightly TOO EARLY in relation to the backing track that i put there beforehand. that happened on many tracks so i know it's not a coincidence. I even reinstalled Pro Tools and it didn't fix the problem for me. another one is - i used to get master fader with the started sessions now i don't. i put them in manually but id' love them to pop in by default. another problem is - i have no idea how the two first knobs are supposed to work and i have a suspicion they don't work like they should? the first one works like a volume knob, gets louder all the way both o my monitors and headphones same way. the second knob though works like a volume knob as well but only half way through and then second half turn doesn't really do anything. Could i ask you to help me with these problems otherwise i might have to go back to using Cool Edit Pro.. gulp...

What exact version of Pro Tools are you running. I recommend 8.0.4 with cs2 and avoid working at 48K(until Avid provides a fix for the known timing issue in 8.0.4, and still in 8.0.4cs2 at 48K)

what is cs2? i updated 8.03 to 8.04 straight away when installing pro tools and it was working fine on it, what else do i need to check?

This is a known issue with 8.0.4. cs2 solves it for all sample rates except 48K. Updates are here:

oh thanks a lot! i'm gonna install it and then see if it fixes my other problems (like click track getting out of the rhythm all the time)!

Exactly what happens when you attempt opening? Did you install anything other than this update? And are you using the latest driver? On another somewhat related note; ALWAYS clone or image your system drive before allowing any modifications to your hardware or software.

I have only installed the 8.04 cs2 software first and audio drivers then. That's my computer. i'm on 8.04 Pro Tools LE Processor Model : AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ Speed : 3GHz Cores per Processor : 2 Unit(s) Threads per Core : 1 Unit(s) Type : Dual-Core Integrated Data Cache : 2x 64kB, Synchronous, Write-Back, 2-way, Exclusive, 64 byte line size L2 On-board Cache : 2x 1MB, ECC, Synchronous, Write-Back, 16-way, Exclusive, 64 byte line size Computer Platform Compliance : AMD LIVE!

Yup. I was just going to suggest removing the Micron memory module:rolleyes:
