When i am trying to log in i get this message:

"We're having trouble connecting. There maybe a problem with your internet account or the Second Life Grid"

so i cannot log in.

My internet connection works fine.

What this message means and what can i do?

It sounds like a firewall or your router is blocking some of the ports needed for SL to connect and function, please see this page for the ports you need to open to allow SL to work.  http://wiki.secondlife.com/wiki/Configuring_your_firewall

That page also provides some help to configure some types of firewalls and devices if in doubt consult the manual for your firewall or router.

Try logging into a different location, if that doesn`t help try clearing your cache manually, go to:

(XP) - C: - Documents and Settings - (USER NAME) - AppData - SecondLife
(Vista) - C: - Users - (USER NAME) - AppData - Local - SecondLife
(Win 7) - C: - Users - (USER NAME) - AppData - Roaming - SecondLife and Local - SecondLife

Rename the folder Secondlife2 and then restart your computer.

NOTE: You may need to go to Windows Tools > Folder Options > View & enable Show Hidden Files/Folders, in order to see AppData folder.

After your reboot, change your start location on login to Smith and when you get in just stay there under the water until your inventory has fully reloaded. You can open your inventory and type in the inventory search bar to prompt loading, but do not do anything else until it is done.

Welcome to Second Life Answers, Talos. With that particular message, I would always check the Second Life Grid Status first

http://status.secondlifegrid.net/

There will be times when logins fail; for example, often on Tuesdays and/or Wednesdays, there is grid maintenance work that involves restarting regions. Occasionally this can cause login failures (this would appear on the Grid Status page).
