Vertical Radius

I've already purchased the full version of GM4Mac, but I don't know where to put it in.

Whenever I start up Game Maker it just asks if I want to purchase it or start the trial version.

I don't want to do either, I want to use my full version which I've already bought...

Anybody know what to do?

Since I can't locate GM7 for Windows since I want to make my game compatible for Mac without making it twice, when will GM8 for Mac come out?
Is it even being made or are they completely neglecting the Mac market entirely?

I'm trying to download Game Maker 7. Yes I know GM8 is out, but I need GM7.
So I go to this page...

But when I go to download any of the versions it takes me to this Upload File page which is weird.

So how do I get GM7 again?

I overheard that GM9 is in production and will feature cross-platform compatibility with Mac, PC, and some mobile devices.
I was wondering if this rumor was true, and if so, when could we expect this to be released?
I'm in the process of making my next game and I would love to upgrade from version 7 straight to version 9 and even have the chance to put my games on devices such as iPhones, etc.
Currently I'm using version 7 as it allows me to easily convert my PC games into the Mac format so that it can be played across both platforms.

Another question about Mac and PC compatibility, I've never tried but can you possibly play multiplayer between the two platforms?
Like one person playing on a PC can play the same game with someone who's on a Mac?

Also if anybody has any other information regarding the compatibility between Mac and PC with Game Maker I'd love to know about it, as I refuse to develop for only Windows operating systems.

Thanks in advance,
