foxyproxy

I paid for my subscription and was enjoying it when it crashed and I keep getting this message:
Proxy Server Refused Connection
Firefox is configured to use a proxy server that is refusing connections
The browser is configured to use a proxy server, but the proxy refused a connection.
* Is the browser's proxy configuration correct? Check the settings and try again.
* Does the proxy service allow connections from this network?
* Still having trouble? Consult your network administrator or Internet provider for assistance.

PLEASE HELP ME!!!!
