After entering the serial no. yr pc should load the boot recovery driver. On yr tab u should see in white letters "entering download mode" this is apx mode. Yr tab will go black. (The white light on the power button should be on) and on your pc u should see the green bar.
I'd say the drivers aren't loading properly, which sometimes happens with xp.
Try running test.cmd first, if u get the serial no. run dotnetdetecter.exe and do not
disconnect yr usb cable. See if the boot recovery driver loads after inputting cpuid and hopefully youll get the entering download mode on yr tab. You should be good to go.
Failing that, running it on win7 will solve yr issue. Or if u can't wait try using the unstable chinese rom as per previous poster
