Error using S-function and dsPIC Blockset

[Mateo]

Hi all, I'm new to the forum and use the dsPIC blockset.
I have encountered a problem I can not solve for hex code generation for loading into the microcontroller 24fj128ga010 when they build it from simulink, this shows me an error (the blockset is a non-inlined s-function) and I suggests that change the current configuration, but in the settings panel I can not activate the checkbox for this Deactivate and I can not activate. My problem started since I decided to enter a s-function blocks in Simulink. I have to enter the s-function for my project. If anyone has any idea how to fix this problem I'll be eternally grateful, and I have a week trying to fix it without getting success.
