Criminal Records without TECRO's stamp, what to do now?

Hi Guys

I have a problem, I don’t know if you already had the same situation,
But I’m applying for resident certificate in Taiwan now.
When I was still abroad, my brother (who is already here) told me to bring a criminal records, but he forgot to tell me to take a stamp from TECRO before come to Taiwan. I did everything, but take the stamp.

Now what should I do?
Do I have to send the criminal records back to my country to take a stamp, or I can take something similar here in Taiwan?
If I send the document back, will take at least 10 days to solve this problem, is too long time.

Regards
