i think i now understand but from my undestanding.

.token+12 should contain the address of .attr

since .token is 4bytes
followed by luid which is 8bytes
then .attr.

please explain

im confused Sad

i think i have a poor understanding of x86 addressing

The +12 is because there are already 3 dwords pushed ahead of it (the three ,0,0,0 that follow it are pushed before it) so ESP has been decremented by 12 bytes. So actually the address is still .token.

A debugger will show you the push order and the addresses that are used.
