Bounce Address used as Reply To Address

I recently changed the value for my Bounce Address (Configuration->Email) to be different than my Reply To address. If anyone replies to a HikaShop-generated email, their email is sent to my Bounce Address instead of my Reply To email address.

I am using HikaShop 2.0.0 downloaded on 28 November, 2012.

Can you edit your email via the menu System->Emails and check that you have the correct email addresses or no addresses there ?
That would explain why it doesn't use the emails in the configuration properly.
