Error -46?

Can anybody give me some help.
I've been trying to download Combat Arms but every time it starts downloading the different (.rez) its says error has occurred than exits out and says error -46, who can explain this to me? Ive tried reinstalling, recovering my computer, turning of anti-virus but no matter what I do it keeps giving me the error and its pissing me off because I have a gold account that I cant even use now..

reinstall a new setup because the setup is corrupted

Ive actually tried that, but every single time I try to it does the same thing..
