Dear Khan,
It is still listed in ISI Master Journal List. You can check from the following link;

Removal from the Impact factor list is a normal and regular phenomena of ISI to keep the Journals on track. In my view your Journal will regain its impact factor – although not so high – in 2015 or in 2016.
Best of Luck
