TOPIC: Paid Registrants not showing on back end

Hello
I bought and installed dtregister yesterday. When using the paylater option everything seems to be working fine. However when using paypal it won\'t update on the \"registration manager\" page in the joomla component backend. The info is in the database however, and it is in the \"ipn_logtxt\" file in /components/com_dtregister. I\'ve tried it in the sandbox and a live transaction and I get the same behavior. My install is
dtregister version is 2.2.6
I\'m not using godaddy hosting
Database Version: 4.0.27-standard
PHP Version: 4.3.11
Web Server: Apache/1.3.37 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.11 FrontPage/5.0.2.2635.SR1.2 mod_ssl/2.8.28 OpenSSL/0.9.7a
WebServer to PHP interface: apache
Joomla! Version: Joomla! 1.0.12 Stable [ Sunfire [eCommerce Edition] ] 25 December 2006 01:00 UTC

Any ideas?

Thanks
Greg

PS: I did a csv export, and the record, which is in the database, of the live transaction which is not showing up in the backend, is also not in the csv export. don\'t know if thats a clue or not, just trying to report everything!
