A question that might have already been asked.

I have a problem and I am not sure where to ask it or if it has been asked already. I am running limewire, 4.10 ( i think). I can start it without a problem. I do my search and find what I want to download. It starts downloading. Everything is fine. Then I leave the computer running and downloading. When I get home from work, I have an error message regarding a firewall and port 4346( or something). The limewire screen is totally grey. I click on the error message, but my task manager says that lime wire is not responding. My computer is not working properly and i cant shut down limewire. My only option is to turn off my computer, which causes me to lose my incomplete downloads. What advice can you give me please. Thank you.
