Done with no success! But thanks anyway for your suggestions.

Do you all work for Limewire? I sent a note to them and they said I would receive a message shortly (it's been about a day now) but maybe they'll have some solutions.

Its probably something to do with this computer or a conflict with another program or a network problem. I thought I'd chance trying to install it on another computer last night and it seemed successful (although that's how it was on this computer earlier too). It's been running all night and I've downloaded several 700mb files and some other large ones and it was still going this morning. I had the second last version on another computer but other programs crashed because of it. I guess I'll just submit to having (trying) it on the computer its on even though it isn't the ideal situation.
