Copy live application instance to laptop ( Ax 4.0 )

Dear all,

I have problem when copy application instance from production server ( live ) to my laptop ( XP SP 2). On my laptop, I installed SQL Developer 2005 SP2 as DB. Dynamics Ax 4.0 installation was succesfully, but when I change application instance ( standard ) into live instance, it generates error like this :

Errorr executing code : xInfo object does not have method “webSession”.
Stack trace

(C)\Classes\xInfo\webSession
(C)\Classes\Global\webSession - line 13
(C)\Classes\SysFlush\Data\Main - line 8
(C)\Classes\ReleaseUpdateRunning\start - line 8
(C)\Classes\Info\startup - line 38

Are they any solution to solve this problem ?

Regards,

J
