Hi,
Thanks so much for your reply but I managed to fix it about five minutes after I had posted on the forum but couldn't find out how to delete the post. Anyway, what I had done was incorrectly updated to the new version from the flashing message on the bottom on the search screen. I thought I had bought the basic Limewire and tried to upgrade that. Yep, nuts I am. I did notice that the flashing message was still there and wondered why so I clicked on it, had a good look at everything and realised that I have bought Pro so upgraded to the new version and it started working straight away. A little knowledge is dangerous, isn't it? So, thank you so very much for your post and I hope I have the sense to do anything which needs doing properly next time. Being a new user, I am still finding my way around.
Take care of each other...
