image verification fails after upgrade

OK, I just upgraded but for some reason the image verification does not appear to be working

If I go directly to /components/com_chronocontact/chrono_verification.php I don't get any output and if I change the header to content-type text/html no error message is displayed.

Any ideas on how to fix this one ?

Thanks,
Nic

reinstalled and its working now - must have been an error during upload
