The whole situation starting with Itunes 11, ending with updating system?

Question

Here's the whole deal:
Put in an itunes gift card. I hit the buy button, nothing happens. I call apple tech. They tell me to update to Itunes 11. I attempt to do that, Itunes 11 tells me I need to run 10.6.5 or later for that to work. I'm running 10.6.2. I do the software updates, they don't take. I tried again today and was told I need to remove files from my startup disc on the machine to create room (except i've already done the updates). I am confused and have no idea what I need to do to fix.
Any help is greatly appreciated!!

Soo, maybe it isnt possible bug, but the way Apple have changed iTunes when going to v11. Stooopid
Anyway, found this link about downgrading to an earlier version. I've just completed it and found one or two "errors" in the method, which I'll detail below

In the latter part of the instructions
11) Open your iTunes Music Folder.
If you never moved your iTunes folder it’s located here:
Your HD/Your User/Music/iTunes
Or go to the Finder type:  Command + Shift + G
Paste this into the the dialog:  ~/Music/iTunes
If you moved it to another hard drive, you will know where to locate your iTunes folder.
12) Open the “Previous iTunes Libraries” folder.
13) Find the most recent copy of the “iTunes Library 2012-xx-xx.itl” file.
Normally it will the last file at the bottom of the list.
14) Drag a copy of the file into the iTunes folder.
15) Delete the “iTunes Library” file.
16) Change the name of the “iTunes Library 2012-xx-xx.itl” to ”iTunes Library” with no .itl extension.
In #11, I simply went to "My HD"/Users/"My User"/Music/iTunes
Copied the latest .itl and moved it up a directory level
The old file in #15 is called "iTunes Library.itl" - which I renamed, and renamed the copied version back to "iTunes Library.itl" = though I do have extensions showing, some people may not and hence wont see the .itl
Anyway all is fixed in my world, and when I launched v10.7, it asked me if I wanted to upgrade to v11 - I said No and not to prompt me again. Playcount issue is resulved, as is changing SmartList criteria with playback continuing
Apple - please correct these bugs before releasing any new versions of iTunes... you've made a very large number of people unhappy
