When you look at your GoVideo list using the Chrome Extension, you can see a list of the previous videos that have been recorded on your account by pressing Videos.
You can see a few videos in here (or none at all) but not all of the ones that you remember recording.
When you sign up to GoVideo through the Chrome Extension, you have the ability to use any email address.
It's possible that you have access to more than one personal or company email address. Therefore you may have previously logged in to GoVideo with another email address and have videos across these accounts.
Check to see the email address with which you are currently logged into GoVideo. Click on Settings (the gear icon) and scroll down to Account.
If the email address is different to what you were expecting, then Sign Out and log in with the appropriate credentials
