Crom Technology — they have filed a case against me.

I have been watching their videos regularly. But on sunday i didn't receive any new video but they didn't tell me earlier. And one day i forgot to watch all the 150 links but they didn't terminate my account. So i thought everything is ok. But suddenly i started receiving calls from lawyer but i ignored it. Now i m receiving emails that they have filed a case against me and they will send a legal notice to my address. Plz help me out plz. I m a student.
