ok, i made a call to Playonline and they solved my problem. THere is a number to call at the end of the instructions booklet. call that number n tell them the problem that u have. they will give u the instructions to unlock the system.
Sorry that i cant post the solution here. cos its been almost a mth or so since i did it n i cant remember.. ... but its pretty easy... juz follow their instructions..

good luck w it.. !!
