I see I have created a misunderstanding:

I am not asking where the test version is, but thank you for the hint.  I spotted the download link for the test version (I did not repost it because as jezzer pointed out, it's not widely publicly available for a reason).  I only posted the current link to the current AM download to reference from where I was getting my timestamp info.

I assumed that the expiration notice was telling me that the new, non-test version of AM was available for download.

If that is the incorrect assumption, my answer has been given and I will wait for the update to be posted in the non-test form.

ETA: Upon re-reading kissing_toast's post:  In the past, my version of AM has only expired when a new one has been released. From that, I supposed that AM actually phoned home enough to get the memo that a new version was available, not that AM was psychic.  It seems that is where I am failing, so I will go back to sitting quietly and waiting...and marveling at how coincidental it's been that AM always expires when EA puts out a major patch and AM is updated.  (Seriously, if that's coincidence, I really am marveling and not sarcastic.)

This is not so much an AwesomeMod bug report as it is an AwesomeSite bug report.  I received the alert informing me my version of AwesomeMod would expire, which made me very happy as I assumed it meant I could update to 1.38/SN.  I assume this because generally, a new version of AwesomeMod is specific to the newest patch from EA and I better update or be trampled.

However, when I updated to SN and downloaded AwesomeMod, the version was last updated August 03, 2012, and is not compatible with 1.38/SN.  In searching MATY to find what dumbassery I had committed, I found that there is a test version, but it is not widely publicly available (that is to say, I assume that's not the version I should be downloading and installing).  

I figure either: a) I assumed incorrectly that the 'update now!' message meant that AwesomeMod was now updated for 1.38/SN (Edit: ding ding ding!) -or- b) The new version of AwesomeMod isn't actually posted yet.

Of course, there's still c) I'm an idiot... but I really did search my ass off, cleared out all my old versions of Awesome, downloaded from all three mirrors, and finally am staring at http://www.moreawesomethanyou.com/ts3/hax/ and see that its timestamp is indeed Aug 03, so I think I did as much as I could do before I actually posted.  In any case, I am now in a sad state of running without AwesomeMod and would like to know if it's a/b or c that's going on here.

Edited to update where I went wrong:  I assumed, based on the coincidental timing of past expiration dates, that AM phoned home enough to get the memo when a new version was released, and that if I got an expiration notice, there was in fact a new version available for me to download.  That appears to be the incorrect assumption that led to this post, so I'm set to sit pretty till the non-test 1.38 is released.  Thanks!
