Posted January 23, 2014 You can also try clearing your Java cache and Wurm will be re-downloaded next time you fire up. Goto Start, then Control PanelFind and click Java.The Java Control Panel will open upOn the General tab (default), click on the 'Settings' buttonClick on 'Delete Files' on the screen that opens up (Temporary Files Settings)Tick every box and then click on 'Ok'There will be a short pause while the files are deleted. Run Wurm again and let the files be re-downloaded. Share this post Link to post Share on other sites
