dll's D167 and S166 are not functioning in keil v2.38??

Dear Sir/Madam,
I am sending CAN messages to our sofware using CAN controller of Infenion C164CI (16 bit) simulation provided in Keil.
CAN messages sent from Macro script(*.ini) are read correctly in respective CAN object registers in Keil V2.14
But in Keil V2.20a, its not reading.When i replace dll's(D167.dll and S166.dll) of Keil V2.20a with dlls of Keil V2.14, it works perfectly as per my requirment.
Can anyone please help me , whether its problem in my approach or its something to do with Keil v2.20a dll's(D167.dll and S166.dll)??

(My Macro file is as below):
SIGNAL void cansend()
{
While(1)
{
sendmsg1();
swatch(.00025);
sendmsg2();
swatch(.00025);
sendmsg3();
swatch(.00025);
sendmsg4();
swatch(.00025);
sendmsg5();
swatch(.00025);
twatch(clock/50)
}
