Where it says File Name in the above image you type in the folder address such as the example given. Then press the Select button.
Kmer is Cambodian language, has some similarities to Thai. I was very interested in Asian culture & language.
Another example is to type in C:\Documents and Settings\"your account name"\Shared which is your downld folder by default.
Did you get your LW from here?

I'm thinking there's something wrong with your installation. Go to Start menu>Programs>Limewire>uninstaller. And uninstall. Then downld LW again but save it to your computer, don't install over the net. Same applies to Java. Perhaps if you downld Java to your computer after uninstalling Java, then re-install it. Find Java here:

I think if you re-install both Java & LW from your computer (not over the net), then the problems will go away (fingers crossed.) Something's definitely not right! Needs at least another go at least!
