For starters, this belongs in the help boards since you're seeking assistance, but a mod will move it ^^
Now then,
There's some things that you can do.
- Make sure you got the updated version of FH.
Make sure you installed / downloaded it correctly.
- Make sure you reset your character's homes and then sent them home via user panel.
- Make sure you logged into the login tab when you click 'Play Game' from the navigation bar. Keep that tab up ~!
- Make sure your connection is strong.
- Try restarting your router.
- Run the game as an administrator.
These are just things from the top of my head ^^
Edit: Compare me and Arctic in case we missed something, Lol.
