Are you connected to AOL (version 6.0 or above) when you try to run LimeWire? If so, Limewire usually takes anywhere from a few seconds to a few minutes to connect. If nothing is happening, your computer may not like the Java 2 JRE. Go here for more information on an alternative version:

Hope this helps! :-) Post again if you need more help.
