[TYPO3-shop] Transaction ID could not bed generated

[Henrik Fosgerau]

Dear list

I'm setting up a webshop with tt_products and a payment gateway from 
QuickPay.

I get an error message on the payment page - the marker:
###MESSAGE_PAYMENT_SCRIPT###
is replaced with:
ERROR: transaction ID could not be generated

Any ideas about what causes this message?

My setup:

TYPO3 4.2.6
tt_products 2.6.1
paymentlib 0.3.0
paymentlib_quickpay 0.1.3
table 0.1.32
div2007 0.2.4

Thanks
Henrik Fosgerau
