Here are steps to bypass the error "xxxxxxxx bytes exhausted".
1.) Open init.php located at /admin/com/init.php
2.) Go to line 208 (or search for "memory")
3.) Change the value of ini_set('memory_limit', '64M'); to a value higher than what the error expresses.
E.g. If your error looks like "67108864 bytes" try something like: ini_set('memory_limit', '128M');
