nitrious09,

There are no central servers. The servers are the people that are connected to the network who are sharing files. If you can connect only at certain times, maybe your ISP is doing some kind of throttling/blocking during peak times. Some do. If you give us your system details then we might know a bit more: System details - help us to help you -> Provide these details when you post!!!

Sue Ramsay & dmdahn,

Try the fixes in the thread below. If nothing there helps, post back with your system details (see for thread for more info about the details that we need).
