Error while registering in TRACES

I received a TAN recently and registered the same in Income Tax efiling login as a first time TDS Deductor.

I have deposited and filed the TDS return for one quarter, but while registering in TRACES I'm getting following error:

• Already registered on e-filing site.
• Invalid Details could be because of
• i. TAN Not Available in TAN MASTER OR
• ii. All the statements filed for Financial Year 2009-10 and onwards are in cancelled state OR
• iii. All the statements filed for Financial Year 2009-10 and onwards are NIL Statements (having ALL challans with amount=0)

Its been more than 10 days since I filed the return.
