Maybe it's too late, but I've just successfully implemented session creation on C# and I can share some experience. According to ICQ desktop client source code they form URL signature a little different as below-

"POST&" + UrlEncode(url) + "&" + UrlEncode("param1=UrlEncode(value1)&param2=UrlEncode(value2)&...")

So I guess you missed url-encoding in some places.
