Not Able to access GPIO or compile mini6410 solution

SureshINDIA
Urgent Help:
I have tiny 6410 with SDK and 4.3inches touch screen. I have installed the
VS 2005 , Updates, Windows CE , with updates, R2, R3, QQ etc as per user
manual on my Windows 7 Home Premium System. I am not able to successfully
compile the MINI6410 sdk or the clean sysgen procedure as per manual. 
I tried even on a XP machine with build always failing. I want to generate
a screen which will show the number of times USER Key is pressed.( K1 to
K8) (USER BUTTONS as per the TIny 6410 user manual Ver 2.0)
the keys are mapped as follows
K1 K2 K3 K4 K5 K6 K7 K8
EINT EINT0 EINT1 EINT2 EINT3 EINT4 EINT5 EINT19 EINT20
GPIO GPN0 GPN1 GPN2 GPN3 GPN4 GPN5 GPL11 GPL12
There is a USERKey.cpp and UserKey.h. I am trying to use them without
success. The Wince Image file which came along with the board has a Button
Testing Program which shows the button pressed. But the source of this
program is not included (or I am not able to find it). So how to write a
custom program to access the User keys like the Button Testing program ?
Thanks in advance
