Logic 5: How Do I Know What Will/won't Expire? Options

[lostchild]

Hi. I'm an amateur Logic user. I just installed Logic Audio 5 on Mac OS 9.2 with a few plugins and virtual instruments. I'm getting used to Logic, but what I don't like is that in the pop-up menus it doesn't make any difference between demo plugins (that will expire sometime), already expired plugins and active plugins that I own and I can use freely.
Is there a way to make Logic show only active plugins and not the demo/expired ones?
I have the same problem with filters and EQ for example. Some won't work because they're expired. Some work, but how can I be sure they won't expire sometime?
Thanks for helping me!
