Vugen issue

Hi

we are facing a issue while recording a script. we are using Vugen 11.00 on windows 2008R2 server with IE 8. We can record the script but once script recording is done there is nothing written Action.C or vuser_end or vuser_init. We can see some thing like below in Action.c files. Can someone help me on this and let me know why it is not writing any scripts.

Action()
{

lr_start_transaction("Login");

lr_start_transaction("Cart");

lr_end_transaction("Cart",LR_AUTO);

lr_start_transaction("Catalog");

lr_end_transaction("Catalog",LR_AUTO);

lr_start_transaction("Logout");

lr_end_transaction("Logout",LR_AUTO);

return 0;
}
