You can get Winamp back again to be the default by opening Winamp and selecting Options then preferences. Up the top where it says setup, select file types. You then can see the available file types that are selected. Go through and select MP3 or whatever file you want to load default with Winamp. Make sure "Register Types On Winamp Start" is selected also. You should be able to load your files with Winamp now. As for the first problem, I'm not sure, beacuse I don't like Real Player that much and never used it. Hope this helps you anyway.
