MCS+ ICD stops for no apparent reason?

I am using MCS+ and its ICD to compile/run a PBP v2.6 program on an 18F4550 that is installed in an EasyPic6 development board.
The ICD compile works OK and the burn of the program to the chip is OK. I have a PAUSE 10 statement at the start of the program so I can step from there in the ICD. My applicable code excerpt is posted below.
Everything works OK as I step through the statements until I get to the TRISE = 0 statement. At that point the ICD stops and displays an ICD error message box saying that it can't proceed because there is an ICD Address Mismatch ("microcontroller is communicating different address information from those contained in the debug files").
I tried reprogramming a couple of times and get the same results.
Can anyone tell me how to fix this?

Code:
