ITunes Match has been crippled on iTunes 10.7. Anyone else experiencing this? Please help!

Question

Running iTunes 10.7 on 10.6.8
So, I am still on iTunes 10.7 (yes, I have been with iTunes 11 and have tried iTunes 12, but in my opinion, 10.7 is hands down the best version of iTunes to date).
I have been using iTunes Match on iTunes 10.7 for over a year without issue. Anytime I launch iTunes or wake my computer up from sleep, it automatically starts doing an update and any new songs are instantly added to the cloud. It was reliable and worked flawlessly until about 4 days ago.
A few days ago when things started acting weird, the first thing I noticed when I opened iTunes was that it no longer updated iTuens Match automatically and the iTunes Match tab was missing under the iTunes Store tab where it normally always appears.
I manually tried updating iTunes match by going to the top of the page, under Store < update iTunes Match (at the top of the page) than iTunes Match appeared.
It did the 3 step process, but once you hit 'done' at the end. The iTunes Match tab disappeared The iTunes match column disappeared and if I right click any of my tracks, ALL my music had the 'add to iCloud' button (files that were already in the cloud).
I didn't lose any of my music. On my iPhone, all my music still appears when I have iTunes Match on.
Here is what I have tried to fix the problem:
1. Completely removed my Apple ID identity from iTunes: Turned off iTunes Match, deauthorized the computer and signed out of the Apple ID
2. Removed iTunes Store cache and quit iTunes
3. Did 'repair disk permissions' in disk utility
4. Changed my iTunes folder to 'iTunes 2' so it would create a new iTunes folder. When I opened in the new iTunes. It was a blank slate. When I reauthorized my computer and turned on iTunes match, it still wouldn't work. When I hit 'update iTunes Match from 'store' at the top of the page, it goes through the 3 step update, but once it is done, iTunes match disappears and none of the songs in the cloud appear (this is what leads me to believe that maybe I am not alone, and maybe Apple has stopped allowing iTunes 10.7 users from using iTunes Match)
5. I once again did step 1 and 2 and re installed iTunes using the saved DMG file.
6. I did an smc reset (this was a long shot chance of doing anything, but I wanted to exhaust all my options)
7. Restarted my computer
I also noticed that you can now longer download the iTunes 10.7 file from the Apple downloads page. When you try to download, you get this error message:
An error occurred while processing your request.
Reference #30.7ed16bd1.1425254177.1b62a8 
This is another possible signal that worries me. That Apple maybe removing online tools like iTunes Match on older versions of iTunes.
Is anyone on here still on iTunes 10.7? Is iTunes Match still functioning normally for you? Do you have any tips on what I can do to fix this problem? Are there any library or preference files associated with iTunes that could be causing the problem?
Any suggestions are greatly appreciated!
Thanks in advance.

Happy to report that iTunes Match has returned to working like normal on iTunes 10.7 on my computer today. If any iTunes engineers read this thread, I really appreciate the fix.
Has it returned to normal for you?
