[xiaoyun153]

Hi,
I am new to Pro Tool and M-audio and I just bought fast tack usb and it came with a pro tool m-powered demo with it..
my system is,
Window XP SP3
Intel(R)
Pentium(R) D CPU 3GHz
2.99Ghz, 1GB Ram

I install the Fast Tack Usb driver software and then i installed m-powered demo but when i start the M-Audio Driver Installers that is for the fast tack usb it tells mi tat my com's operating system is not supported for use with the fast tack usb at this time... and when i dun install tat and install M-Powered Demo Setup without it. When i start the program they say the cant detact hardware but i have plug in...
I have been doing this for many days and look at many post but i still dun understand how to make it work!
Really need help badly!!! Or i have waste my money on fast track!!!T_T

Thanks Alot!!

Have you tried downloading and installing the latest drivers available at the M-Audio website?
