The advice will be slightly imprecise because you have not told me which computer you have, what operating system or which version of Limewire you are using. I shall make the assumption that you have not downloaded either an upgrade of Limewire or of any other application that might require modification of your operating system (if either assumption is incorrect, this advice may be incorrect and different action might be required).

I am alarmed by your statement, "I have tried to let it download for as long as 3 days and it does nothing." It suggests that you have completely misunderstood my first post. You cannot sit there and watch the download fail. You have to take remedial action. There is no automatic reconnection to the host. You have to kill the download and restart the download from the original hit on the search page (which you have carefully kept available). Assuming that the host has not shut down his/her computer (which may be the reason for the failure), restarting the dowload will usually reconnect you to the original host. If not, leave the stalled download in the download box and repeat the search using the same typography. That will often refresh the connection. There are many other practical measures that you can discover through experimentation.

And as to your suggestion that you should have a refund, I am surprised you should feel that five months of valuable service is an inadequate return on your initial outlay. No shop or business in the Westernised world would consider such a request reasonable.
