ok i downloaded an earlier version of LW and it worked perfectly. so i go and download the newer version everything goes smooth, but when i try and run LW it comes up then it just closes. the computer i have is a windows 98, what should i do?

You can try these fixes...
Try uninstalling all versions of Java from the add/remove programs and then re-install the JRE 5.11 offline version....

If that does not help with your problem try deleting your preference folder/s...This will reset your configurations back to default and get rid of any corruption that may of happened...;)
