If you can't find the offsets, then chances are either some pointers have changed, or some relative addresses have changed, or some offsets (in the opcode, so immediate data) have changed. So you could try using some wildcards in your AOB '??' or debugging it and finding the new offset that way. And if that is the case you'll need to fix up a little bit of the scripts code, otherwise it could be that the entire function is different so you'd need to write an entirely new script.
