Korkie1974 Hi.

First, Cut & paste your 4.9.28 L/W installer to desktop or somewhere safe.
Follow these 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.
Apart from your 4.9.28 installer, 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.

Now! Use this Link to get (jre-1.5.11) Use the off line installer, NOT the (recommended) one,
Java SE Downloads - Previous Release - JDK 5
When Download is completed.
Disconnect from internet, close ALL apps n reinstall java.

I would recommend this next bit, But if you wish to use your old 4.9.28 reinstall it now.(if that don't work,install the new one below)
Now!! Use this link to download latest L/W version using the off line installer
LimeWire
If you need help, Shout, If it fixed your problem or not, Feedback helps others.
Peace
