There's a link on their announcement. Basically you just tell them your purchases and sales made during the period in question.
Keep in mind, based on my quickly reading the announcement, you have to have a net loss for the period in question. I did really well a couple of times last year with these shares, so even though my current play is under-water, I wouldn't qualify even with a 100% loss on these halted shares. How they are valuing the halted shares is also something I'm not clear on.
The only other thing I can say is don't dream of getting much back. Lawyers aren't cheap! On the other hand, you don't have anything to lose either!
If you need more accurate information, there are other posters here who are quite knowledgeable so just ask again!
