I don't know if this will help but I ran into a similar error setting up TS3 on another PC running Windows 7 x64 today. It turned out I had it installed in both Program Files (x86) and Program Files and it was running the wrong (i.e x86) version!
So that might be something to check. Other than that, this is what my plugins folder under Program Files\Teamspeak 3 Client looks like. It seems for some plugins (ACRE, TS3 Overlay) it puts both win32 and win64 versions in there and must just ignore the win32 versions but as you can see, for the whisper plugin I just have the x64 version in there (obviously if running Windows 7 x86 you need just the whisper_plugin.dll as Horus said).
