Singers' disc function

[WDEWDAD7]

I have Hoster 3.316, and the problem I have is: all of a sudden, when I go to input a singer's disc, I get a message stating that my C drive is full and recommends I empty my recycle bin. My recycle bin is empty. Plus, if I retry it, it then gives me a message stating that the import is already in process...and nothing happens. I then have to close and restart Hoster to continue my show. Hoster will not work until I do so. So, when a singer brings their own disc, Hoster won't accept it. I have done all of my updates, discs cleaned, defragged , etc. Has anyone experienced this before? And if so, how did you remedy this? I have a 250 g drive, with 52% free space. There is nothing there to take up any free space. Thanks in advance, Daryl.
