You'll need to run Proteus by itself, or use MPLAB 8.

It's my understanding that it will work with MPLAB-X once Proteus 8 is released.
Do you mean PBP3 does not work with MPLABX+Proteus yet?

I'm happily using Proteus 7.10 with MPLABX C source. I can compile with XC, HiTech and SourceBoost compilers within MPLABX, and MPLABX fires up Proteus and simulates just fine. It's only with PBP that I can't simulate.
