You would have discovered you needed CCPMX_OFF somewhere in your @ DEVICE statement.

If using MPASM you would have needed _CCP1_RB3 in your config definitions.

The clue is in the fact that this is a CONFIGURATION WORD (CONFIG FUSE) setting (see PICs Datasheet) therefore you need to make those changes in your CONFIG Definitions which are burnt into the chip at Program Time.
