I've tried to d/load this demo & it gets to 99% & says error encountered or something. Problem is I cannot remove it from my PC no matter what I try & it's using a precious gig of space up on my HD. I have very little HD space left until I get an external one. How the hell do I get rid of it. It will not remove using the d/load manager & I can't get rid by going into my drive & deleting it manually. It says already in use by another program.Any ideas?
