If probation in CA works anywhere near how it does with my county, you will be ordered to appear for a violation hearing regarding your lack of compliance. As you've already seen, you had five years to complete an 18 month program. The fact that you are already aware of the amount of time that it would take to complete the program suggests that you've at least completed the evaluation. Hate to say it but, you kinda screwed the pooch on this one.
