You should just have contacted Ukyo on IRC, he is usually quite easy to get a hold on there. (unlike here and through support tickets)

If you didn't know then Ukyo set up a portal where users can withdraw some money which Ukyo defines as "available" we can only guess why the rest is "unavailable".
6.175% of the stuck funds are available for withdrawal atm: http://weexclaims.weexchange.co/
