different EIP at different PC ?

[WoZX]

i use TRW2000 to debug a packed program, i got the CS:EIP address to patch, so the bpx always work, but it only worked on that PC, when i use TRW2000 in another PC debugging the same program, my bpx doesn't work ?

anyone can help ??? and tell me why?

btw, i got the hex code, since i do not know the exact new EIP, how do i 'bpx' in trw2000 ?

i have seen a tute like this but have forgot where it was, like this:

bpx cs:eip IF *(EIP) == ????????

can't really remember the syntax, help please !!!
