You need to contact your server administrator or server hosting provider for assistance so that the server can be upgraded to support a more secure key exchange algorithm.

I know this says "closed" and "wontfix", but I'm getting this error message trying to connect to a server that my boss and coworker can still connect to. We are all on the same version of Windows 7, using the same version of FileZilla. Any idea what is wrong with my machine?
