MC9S12XS - No Access to CPU

i have a problem with uploading my program to this cpu. I can't upload a new software?! I use the ic 3000HS from isystems. I tested banked flash and far functions for Paging. This works for a while...

The last time i was debugging, i saw that the cpu executes code that should not be executed.

At winIDEA i found an option unsecure Flash. This works for accessing the cpu and upload the code several times before, but now it not longer works. How can i access to the cpu and erase the flash, or upload a new code. Hope that someone can help me!
