When checking out, a confirmation page should be shown, but isn't.

When customer signs up during ordering, the registration e-mail is sent (and arrived at customer)
After continuing the checkout procedure, the following error message is shown (0 bccomp(): Argument #1 ($num1) is not well-formed).
Besides that, also no order confirmation is sent to the customer.

In the system I can see the order which is placed and continue with it, but the confirmation is not sent to the customer.
Hope you can help out here?

I saw others having the same kind of error. In those topics it was mentioned to install the version from the website. hence I downloaded the latest version today and installed it, but this didn't help.

Thanks,
This works like a charm!
