WoW Patching Issues

[Magtheridon96]

Note: I'm using Mac OS X 10.6.4

I bought World of Warcraft Classic and installed it on my computer. The installer told me to pick between Classic, Burning Crusade, and Wrath of the Lich King. I chose Wrath of the Lich King, and continued ...
I opened up the launcher and it began downloading 8.7 GB (Cataclysm).
I had authenticated my WoW account (Classic only).
The game didn't let me play at all. It forced me to upgrade.
So I went out, and I bought Cataclysm.
I put the CD in my computer, started the installer, created a new folder, and installed everything. Currently, both the classic and Cataclysm files are on my computer (WOTLK and BC I'm not sure, but I took them for granted since the Classic simply installed everything .). The classic is in one folder and the cataclysm is in the other (The installer was going to overwrite everything, and I didn't want to take that risk)
I went to the site to authenticate my Cataclysm key, but they said it was invalid...

What should I have done?
What did I do wrong?
What do I need to do?

Notes:
I didn't buy BC or WOTLK

Please help me guys!
I'm so pissed right now >.<
Every time I try to login (in WoW), they tell me that "My Version is not Verified".

NOTE:
I'M NOT DOWNLOADING 8.7 GB!!!

Possible solution I need to ask you guys about before doing:
- Buy BC and WTOLK, insert their authentication keys without patching them
- Insert the Cataclysm key
- Play

I'm counting on you guys (I already wasted 2 of the 8 weeks I have left )

Umm... You cant upgrade from Classic to Cataclysm without having the other expansions.

You can however play without the expansions but your gameplay will be limited. And I dunno I just installed it from the CD and whenever it wanted to update I updated.

Do you know of a way I can reinstall WoW?

Do you know of a way I can reinstall WoW?

Windows start menu -> add/remove program or delete the stuff manually

Then just put the CD in and well I dont know which one you should select because I just used norm CD for norm Wow and TBC CD for TBC wow and so on.

1. Uninstall it.
2. Install WoW (orignal)
3. Run WoW (orignal)
4. It should now start patching (If like other blizzard games) until it is playable.
5. Play.

I have never played WoW so I am guessing the above as that is how other blizzard games like SC2 work.
You have to download the vast GBs that step 4 requires inorder to play. This is because so much content was added to WoW and so much code changed since the orignal that it is impossible to interface with the new game without updating.

Then with my slow internet (50 KB/sec), it would take days
... Screw WoW! I'm going to have to stick with my pirated WC3 (Strangely I had the time to download it xD)

edit
Thanks for making me realize I should just leave it all behind
Seriously, you can close this thread
In fact, since I'm not going to use the Guest Passes, PM me if you want one (If that's illegal , you may edit this post and remove this entire line)

I do not think you have to download it all at once do you? Just let it chug away at it during meals and when you are not using the computer.

Ofcourse I don't have to download it all at once (I'm downloading at 120 MB/hour, but it's just not fast enough >.<)

I'll try downloading it anyway (Thanks for the pep talk xD)
