Can't re-install Halion 4 on mac

Hi, I bought the Absolute VST collection and the Halion 4 upgrade from the VST Collection. I had a lot of problems with the libraries and following some of the advice here in the forums, I removed everything Steinberg and updated the e-Licencer and reinstalled my Cubase 6.5 and Cubase 7. The problem now is that the installer for Halion 4 will not install the plug-in, (it says 0 KB) in the installer. I’m thinking about downloading the trial version to see if that works.

Can somebody help? I’m in Mexico City and Steinberg does not give email or telephone support here.

My computer is a 17" Macbook pro with OSX 10.8.4
