got hacked now CF doesn't start.

I was playing Mutant mode game in one of the rooms. And one of the player was blocking the entry to prevent other players from entering. So I asked whoever was hosting to kick the player who was blocking.

Then immediately, I was kicked off the server. my guess is that I was hacked...

And now, if I try to restart the CF, I get to the HGW game watcher window but it gets stuck at step 4.

Then I get an error saying "Failed to connect to the server : W[2003] L[0]"

What should I do?
