Firstly, it's really ONLY the CONFIG settings... so nail those and your problems will disappear. If you comment-out all your defines, you'll probably find that the chances are you'll compile without error with a set of defaults. Now, Microchip are changing their config declaration syntax, so this all depends on the version of MPLAB/MPASM you've got. So that we're playing in the same ball-game, go download the LATEST version of MPLAB/MPASM, then come back, tell me you've done it and also tell me the Config Setup's you need. I'll then walk you through it with that example...
