that's the message I get when trying to install Pro onto my Mac. Had Basic installed (and it worked great****** it!) and I've sent it to the trash, emptied the trash and restarted the computer several times

I get the message on the 2nd screen of the istall program which says "Select a destinantion" and shows my one and only hard drive. But when I choose the heard drive it gets a red Exclamation mark and gives me the message.

Any ideas? I'm new to the Mac so still learing.

Thanks
