HTTP Download Problems

[Internetmstr2]

I want to be able to download Counter-Strike maps from my website via HTTP. Plesk wont let me download files with .bsp and .wad extensions. I can download files with .zip and .exe extensions. When I try to download the .bsp and .wad files Plesk says "The requested URL was not found on this server." I've double and tripple checked that I had the right URL and file name but it doesn't work. Is there some setting in Plesk or IIS that I need to change?

My website is clannm.dynu.com and the files are located at clannm.dynu.com/csserverfiles

Did you want to provide a filename within that directory to attempt to download?

You can try to download fy_snow.bmp in the maps directory in csserverfiles or de_vegas.wad in csserverfiles. So thats
http://clannm.dynu.com/csserverfiles/de_vegas.wad
http://clannm.dynu.com/csserverfiles/maps/fy_snow.bmp
