I am glad that at least hoster is working for you now. You mentioned in one of your earlier posts that you had re-installed Hoster 2.219 hoping to fix the problem and that did not fix it. If everything was working fine before you installed Hoster 2.219, I suggest you restore to the time before the intial installation of Hoster 2.219. If you do not like it after you do it, you can reverse it. However, if everything was working fine before the intial install of Hoster 2.219 and you restore your computer to a point before that installation then you could re-install Hoster 2.219 again, making sure that WMP is working properly before you do and making sure that autoinsert notification for all your cd burners etc. is turned off. Also, in WMP make sure that WMP is not the default player for any files except WMA audio and video video files. I would try this before I consider wiping the drive and re-installing the operating system. It's possible that something you did prior to installing Hoster 2.219 corrupted a registry entry and if you do a restore, it should take the registry files back to a point before they got corrupted or an improper entry was made.
Hope this helps
