Is there a limit to the number of AD groups available in the free password notification tool?

i just installed the free tool for password expiry notifications. I want to create a policy based on AD group but i'm not seeing all the groups in our domain. it looks like we're limited to just 2000 available groups to choose from. how can i pick a group that doesn't fall in this first 2000?
