That looks very much like a permissions problem, so that should be the first thing you go through finding the answer.

Check all your security software to make sure that both java and limewire are allowed to create and edit folders/temp files.

One option might be to set Java to Run as Administrator. Likewise set LW to run as Admin.

Try up dating or checking your java at www.java.exe Im having problems also was working a week ago now the icon come up and pop out it goes.. so im still working on it

delete all your old temp files reboot pc and try again
