Gmcs-2 online registration

hey guys.. I have done online registration of gmcs-2 at nirc website and made payment of 5500 also. Since it is the process to make first payment then only we can select the batches. The 48 hrs time has also been passed, but still i hadn't received user id , password.. And it is continously saying your a/c is not yet verified. So guys if any of you know about this, then help me on this issue.. And if u know ki exactly how much tym it will take to get registered. I haven't received any e-mail also. Thanx in advance.
