I see you have quite a few downloads.
even though you do give credit to the owners, i dont see that you have been given permission to host, and make those file available for public download?, even thoug you may be able to download them from other sites, or that they are free/shareware, then you would still need the permission of the copyright owner.
i see you have things like wolfenstein - enemy territory, whitch i know as a fact you have to sign up at their site in order to download. also internet explorer 7, all your antivirus programs and such, i am very sure that you havent been given permission by the copyright owner to have them on your site. this is just to help you from getting quite a few cases on your back :p
also do you know if your host (i see that you host your self and use a free dns subdomain) but do you know if you are even allowed to host those files while using their dns?
i found this in the DynDNS acceptable use policy:

and i like this one

For purposes of this AUP, facilitation of the illegal distribution of copyrighted materials, through operation of a "hub", "tracker", or other filesharing mechanism, shall be considered identical to the actual illegal distribution of those copyrighted materials.
the part in red is what i think would apply to your site.
so bud, please be carefull when hosting these things ;)
in the future, get the permission from the copyright owner, if it does not clearly state that it is allowed to be redistributed.
