restrict a plugin to a specific user guid

i need a little help..... im creating a 2nd blog plugin that will basicly be my news, i have one account on my site that controlls all the news and i want to restrict this 2nd blog plugin to that specific user guid iv been trying this and it kinda works il explain

if ($user_guid == 56) {plugin info here}

ok so my guid is 56 when i use this code it works in the sence that it doesnt show the plugin but the problem is I AM 56 and im not seeing it.....any ideas? i also tried this

if ($user_guid == 56) $guid = elgg_get_logged_in_user_id; {plugin info here}

but still nothing, im pretty sure the function is working its just not recognizing me as GUID 56
