Put the ".mis" file into your "offmis" file, which is in your main AHII folder. I think any ".res" files (if there are any - there usually aren't) should go in the "missres" folder, also located in your main AHII folder. I think but I'm not sure that any other things go in your "ahiiterr" folder, but this may not be correct.
