I can't upload to video portal HELP! IP address / API issue.

I have not logged onto my account in forever and I have forgotten how to upload videos or something.
I go to the submit video and paste my Youtube link but every time I get this error message-
" The calling IP address 65.60.2.250 does not match the IP restrictions configured on the API key. Please use the API Console to update your key restrictions.: ipRefererBlocked "

I have no idea what that means. I need help! What am I doing wrong??

Here is my youtube video Im trying to upload:

Why is this so hard for me? I see that others can upload videos to KH vids, but not me. :/
Please help me out someone. T_T

 

I know this is really late but this error tends to happen a lot after major server changes. I hadn't actually checked it in a while cause i haven't tried to upload anything on it since September. I don't know if the staff currently find this a priority, or if downsizing made it so upkeep of the video portal is even possible.
