Error while buying Grand Inquisitor Lightspeed Bundle

I tried to purchase the Grand Inquisitor LSB on February 8th via the webstore, but I encountered error 54005. After that, PayPal displayed the message: 'Payment will be charged to your payment method once EA Swiss Sarl has processed your order.' At the same time, the LSB is still available in the store. Should I just try to buy it again?
