Hi, I've used LM for a few years but never happened since I download to upgraded LM4.12.6. When I start using new LM, I never preview any music on LM, including saved files, incompleted files and in the middle of downloding files on LM. I can completly download the music and can play in WMP after 100% downloaded as usual but I want to preview music before complete downloding. Cannot preview any music on LM, but can play outside on LM, like WMP. Please advise me how to preview on downloding files. Thank you very much in advance......
