New customers can not register?

[Martinius1979]

I have joomla 2.5.7 and latest virtuemart (12b)

When I trie to register as a customer I get this message:
"The solution of task you submitted was incorrect. Please read the instruction and try again. "  I have tried four times now and I do not do anything wrong - it is not that hard to register as a customer in an online shop.

I am finished with my shop more or less. But I cannot open when customers can not shop

Any idea what this can be?
