I should have read your sig. Doh! I think since you are using OS3.9 you can't use Maprom unless you a using a Custom Rom that you made up. However if you have a Custom 3.9 Rom ijn a file that you made you can replace * with the path to that Rom file and then it will work.
For now, if you do not have a Custom Rom you should take out Maprom all together.
Then you can ask in forum about making a 3.9 Rom, mfilos is an expert here so should be able to give some advice
