Will update on the success of the programming of the welcome message!
After the mod, as explained in the discussion, I am writing leaving all of the sw with the default settings, and gave me an error, and there is a voice to check the chk before writing, I've made the control of chk by mpps and corrected a sector, after which? I raised again the writing and voil? 20sec about made the cancellation and rewrite it correctly!
Again, I thank you for the help given! I hope to continue to learn new things! Especially on the editing of the map!
