Hi Martijn,

As I said earlier:
Before any (read or write) access to EEPROM the EEMEN bit in the WMCON sfr must be set.

This does not seem to be happening in the code you posted above. So unless the EEMEN is set somewhere else, you should expect strange values... ;o)

You can mail me your code if you like and I'll have a look.

Groeten,
Rob.
