OPT got denied and I-20 Completed.

My I-20 was completed on June27 and OPT was pending decsion and its denied on Oct 22nd. I had 30 days to transfer my Sevis or leave the country. I have got admission in other university. I have learnt that now I need to apply for re-instatement, are there any chances of getting it denied? I did not break any law.
