asked to link a cc/debit card when making a payment.. i have enough funds in my paypal though

[oinkoink]

after i clicked check-out from a website after purchasing something for around 44USD, i am being directed to paypal.

when i logged in to paypal, i am being asked to add a new credit card or debit card. [this only happens when i have insufficient funds to pay]

but i had just converted around 50USD on my paypal and i am sure i have enough balance to pay for it.

may i know what could be the problem?

p/s

- i have no problem with making payment with paypal before.

- i do not have a cc/debit card.
