unable to lounch song during download...
 

I had no major problems with LimeWire until yesterday. Somehow the files are not converting to Quicktime anymore, there are only blank pages icons instead. I know I can convert them after the download, but that is not the way it used to be. Sometimes I just download stuff I don´t known and I want to listen to the first part just to decide if I liked it, to continue to download. Please help.
