Windows 7: Why "The settings saved on this computer for network do not match"

Hi - I can connect to most networks (wifi) that I want to but for some reason my office wifi I cant because I get this message:

"The settings saved on this computer for the network do not match the requirement of the network"

Im not sure what to edit here any ideas? Thanks

You can get there by going to the Network and Sharing center, look on the left where it says Manage Wireless Connections, you can open up the profile for that connection then make adjustments to it. You will need to know the SSID, wireless password, the type of security and encryption also need to match.
