Database error sending out Mass mailings

This is the error I get when I try t send out mass mailings:

Query:
SELECT `id`, `email`, `subject`, `body` FROM `sys_sbs_queue` ORDER BY `id` LIMIT 0, 5m
Mysql error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '5m' at line 1

Found error in the file '/home2/thechur3/public_html/inc/classes/BxDolCronNotifies.php' at line 44.
Called 'getAll' function with erroneous argument #0.

Not sure what this is saying to me, i am a noob when it comes to PHP.

Not sure where that 5m at the end of the quary is coming from ?

this should be the right quary:   SELECT `id`, `email`, `subject`, `body` FROM `sys_sbs_queue` ORDER BY `id` LIMIT 0

this is line 44 : $aMails = $GLOBALS['MySQL']->getAll("SELECT `id`, `email`, `subject`, `body` FROM `sys_sbs_queue` ORDER BY `id` LIMIT 0, " . $iProcess);

in /inc/classes/BxDolCronNotifies.php 

Try to replace that file with a clean copy from the dolphin zip file.  just rename yours to something like  _old before you replace it.
