[TYPO3] sr_feuser_register no longer sending emails after updating from 2.5.6 to 2.5.7

Hi,

I have updated sr_feuser_register from 2.5.6 to 2.5.7 on Typo3 4.1.1 
without changing any of the settings and now it no longer sends emails. 
The users seam to be created correctly in the appropriate sysfolder, but 
no email is sent to the user or to the webmaster.What could be causing 
that and how can I fix this?

Thanks
