gua pun sama!!
will go and ask post office clerk bila pi renew roadtax next week...

finally, can go in!!
try masuk thru portal rasmi jpj... "mysikap"!!
select "log in", then select "orang awam"...
it will guide you all the way. they will emailed temporary password. bila dapat, can go back to "log in", and changed password. will take em sometime to process.
after few hrs, can oledi masuk "myjpj"...
