Are you sure?
I've made my comment based on the information you provided, which is that you don't see the Troubleshooting section in the GSX Settings page, and the only possible reasons for this for this are:
1) You don't have the most current version
OR
2) You have it, but you don't see the Troubleshooting page even if it's there.
So, I've started with the most likely, which was #1
If it's #2 instead, then I suggest checking better, because the Troubleshooting page should be there. Note the Setting page can scroll down, the Troubleshooting section is the last one down below, it might not be visible if you don't scroll down the page.
