x264 + nsvate encoding help!

[Spaceb]

Hi guys, I really need your help. This is the deal, I'm trying to encode a xvid file using nsvate, the target format is x264, AAC+ (nsv file). The thing is that I keep getting this annoying error in nsvate. After adding a source file and setting up the encoder I hit "Encode selected" and a window shows up saying: "error initializing x264 codec", I click "accept" then it says "addVideoFrame:vidcoder->Encode()returned error". I downloaded the nsv_x264 dll files and put them in the correct folders (nsv_coder_x264.dll in Nsvtools, and nsvdec_x264 inside winamp plugin folder), I also installed the latest ffdshow and changed the ffdshow video configurator to "set all stable formats to libavcodec", I also downloaded and installed the latest version of x264vfw. I tried searching on google to see if there was a solution but it seems that I'm the first one with this problem! Please help me I tried everything and I already ran out of ideas!

PS: I hope I made myself clear, my english kinda sucks.
