TOPIC: Fatal error: Allowed memory size of /libraries/joomla/datab

Hi i have Updated to DT Register 2.7.12 for Joomla 1.5
My PHP. ini had 64 now 128 MB.
My Joomla installation is 1.5.25
Im Using Kunena 1.6.4, JoomSocial 2.4.1, XIPT 3.3.745, JoomGalery 1.5.7.4 and Remository 3.53.13J as major Komponents.

When a User now likes to register for an event. Typs the details, Reviews all and go to the payment page, Selects the Pay later option, and than clicks to next there should come a pay later tank you page. instead the following error occur:
Fatal error: Allowed memory size of xxx .../libraries/joomla/database/table.php on line 847

than i changed in my php.ini the limit from 64 to 128 but than i get the same error only this time with the time limit.

Fatal error: Maximum execution time of 30 seconds exceeded in /home5/lefriseu/public_html/illusion/libraries/joomla/database/table.php on line 847

Hi guys i found not the error but the depended component. Seams that DTRegister is not compatible with XIPT (JoomSocial Profile Types) after deinstalling it, all works normal again
