Hi thevale.
Well I'm also using NTL and I'm having no problems, But my connection is 4meg.
People that have the package, (TV,Phone,+ free Internet) it seems that you
don't have unlimited, n has some restrictions.
So phone them and ask, also ask, can you give me that in writing, they wont fob you off then.
If they say its not them Try this.
Sounds like things have become jumbled.

Follow thease instructions exactly.
So, you need to Go, Start/All Programs/LimeWire n Uninstall all L/W versions.
Do Not Uninstall From Change or Remove Programs.
Re BOOT Your computer NOW.

Now Go to, Start/Search/click on all files n folders/more advanced options/
& make sure, case sensitive, is not ticked. (all other boxes should be ticked)
Now!!, Put limewire in box, (all or part of file name) & click search.
Delete everything found, including Prefetch folder, (I mean everything)
Re BOOT Your computer NOW.

Now! Go to,
START/Set Program Access/Change or Remove Programs,
now completely remove all versions of java.
Re BOOT Your computer NOW.

Cheers, thanks very much for the help. I've tried everything you've said there, step-by-step and it's worked. No need to ring NTL/Virgin, so it seems they aren't blocking it.

Thanks again.
