Problems buying

[mmm_bleeprin]

Went to buy my PC parts, but when I tried to enter my card number it kept flashing up as 'card no invalid'. I checked it several times, it's the right number, do you know what could be going wrong?

The security on the PC I'm using is fairly outdated, could that be a factor?

Call OCuk or email thier customer support just to check. It has past its expirey date ?

No, well within expirey. I'll give them a ring.
