I am exactly on your same situation and posted the question earlier today but still no reply.
I am from Spain but i live in Taiwan and FormsCentral is not available here either :-(
I really don't know what to do because i kinda need it urgently and the trial free version does not let you do too much...well...lets wish us luck and hope we can get it soon.
If you have any further news or find a way how to purchase it please let me know (ill do the same).
I tried to contact the adobe support by chat on Wednesday. The lady gave a list of resellers and asked me to contact her if I couldn't find it. I tried to do it today, but she is unavailable.
The explanation they are giving is, its an old product and that's why they took it from the online store. I don't think that's a valid excuse.
I am desperately in need of it
Let's hope that someone form Adobe Russia responds to it.
FormsCentral is simply sold through Adobe's online store and is only available in the countries listed in the FAQ below, it is not available for sale in Russia. If you have a credit card with a mailing address in any of the supported countries you can still purchase regardless of where you live or would access the service from.
These are the two FAQs related to this, there are possible ways to work around the issue described in the second:

Unsupported country error:
Josh, Thank you very much for the reply. Let me tell you that neither do I have a debit/credit card issued by the supporting countries nor do I live in the supporting countries. What options do I have? Thanks in Anticipation.
Unfortunately at this time a credit card with the mailing address in a country supported for purchase is the only way to purchase a subscription.
Thanks for the reply Josh.
