windows xp/audigy/logic 5.1

[world_b6]

These are my system specs..

P4 2 Ghz intel
Intel Motherboard d845hv
nvidia 64mb ddr vga card
Creative audigy platinum Ex
1024 sdram
seagate 40gb baracuda HD (7200rpm)
Windows Xp Operating system
Logic Platinum 5.1

I used to work with the creative platinum drv 2, which actually wasnt good enough for the logic. and so, seeing that audigy is 4 times more faster and supports asio and the fact its prettty cheap also, made me buy that one, as a final resort to my recording problems.

well, after installation with none of the crap that comes with creative, with just the suuround mixer and stuff. i started logic, where i gave the option of asio and unticked the pcav facility.

i opened up a file made before which was in 44khz, which it asked to be converted to 48khz. and then i played it, but the cursor and sound just played for a sec and stopped saying system too slow and over load with ref no.s such as 10011, 10009..

first of all, ive spend a lot of money into this setup and iam just feeling like a big loser if i dont get things right.

So, please tell me, what is the best options i could try out, it would be very kind of you..

Thanks
