Soundtrack Pro and Compressor greyed ...

For some reason the option to install Soundtrack Pro and Compressor are greyed out when performing installation of Logic Stdio.

I had installed Logic Studio previously but ran out of disk space and so uninstalled the program, upgraded my hard drive and I'm now at the point of reinstallation - but can't install those two programs.

Here's a screen shot of what I get AFTER installing what I can:

Also, why do some of the programs have 'upgrade' under Action?

Thanks.
