Thunderbird won't load emails anymore since a few hours...

Hi there,

Not sure what's happening here, but I'm not able to pull in my email anymore into my mail program. Nothing loads.
I'm able to send emails, but that's it. I'm using Thunderbird. And yes, I did "repair folder" already, but that just emptied out my inbox.. and it's not pulling anything in anymore.

Please advise.
