If you go to the Apple menu -> Software Update does anything show up?
Find My Mac seems to be full of issues that make it not able to run, very un Apple like.

The only problem I'm having with Find my Mac is that after I remotely locked it (just to check it out) I have a guest account option on the login screen, but in my preferences, it's disabled. i've tried enabling and disabling the guest login but nothing happens. help? thanks in advance

This is what i just found in the Apple forums. I have not tried it yet, but according to the thread, it works.
Run Disk Utility, and Verify Disk.
You will likely notice errors that require you to reboot to the Recovery Partition, and run Disk Utility from there, to "Repair Disk".
After running Repair Disk, reboot to the main partition, and run Repair Permissions from Disk Utility.
Then install the Recovery System Update again.
I bet your problem will be solved.

EDIT* Just tried it and it worked great!!
I have File Vault enabled, which means that a boot password is required upon startup. Is it even possible to have a guest login with File Vault enabled?
If you turn on Filevault 2 it disables the guest account.
