Did you install the english version or insternational version. May I suggest you update your Java: Java 1.4.2 What application are you using to try to open the file & what type of file is it? Keep in mind that if you attempt to open any type of file other than audio or video from the incomplete folder, it will NOT open & yes you will receive an error message. Only video & audio files can be previewed. No attempt should be made to preview/open any other type of file unless it has 100% downloaded & been moved by LW to your LW Dwnld folder. To know where that is go here: LW's menu Tools>Options>Saving & this will tell you the name, location & path of the LW dwnld folder. If you wish this file to appear in LW's Library window, then it will need to be shared. You can add this as a shared folder here: Tools>Options>Sharing & press both Apply & OK buttons when you've finished.
