Battle.net connection problems

I click on Battle.net and it says that there is a problem writing information on my hard drive and i should check to make sure there is room. I've done every thing I can think of to try and fix it. I've disabled the firewall, gone to the warcraft III technical support website, and yes I've checked my hard drive and i have plenty of room. Please help me out.

Some information. I downloaded it by torrent because my disk has gotten all scratched up. I would prefer not to download a new torrent to make it work, but would be willing to if it was the only way. If that is the only way please suggest a good torrent.

Also i have all of the patches updated so please don't suggest that.

Listen, when you downloaded the eurobattle.net euro loader, you should've installed it in the the folder which also had warcraft III forzen throne and not in C drive, secondly you should've installed the gateways too, You should've extracted it in ur warcraft 3 folder and den u shud've run it(the loader file), secondly you shud also install the gateways, dont forget em
