Got bit rather late by the failed BIE KMS thing

Enterprise 7 BIE x86 (not sure which exact one -- N ? E ? or ___ ?)
It suddenly had a blackened desktop, with the 'Not Genuine' message appearing at bottom right.
I believe I may have seen an error message pertaining to the KMS server no longer being reachable (?) Otherwise, this may have been triggered by having to replace a dead CMOS battery and re-input the CMOS data . . . or simply the passage of a certain period of time ?
This is not a particularly recent computer, so I don't think a Win S/N (or Reg. _whatever_) entered into the BIOS could be involved. I think there may also have been some error message about reaching the max. # of re-arms, in the course of trying the BIE-provided remedial files ? There is a vast amount of apps and other custom stuff installed into this rig, so I'm hoping for a way to salvage this situation and not lose anything.

I began with this MDL thread:

25802-BIE-KMS-crack-no-longer-works

moving on to:


19404-Not-genuine-after-KB971033-update-Read-this!

and others, but I'm confused. (I'm nearly certain that I avoided that KB like the plague, so the above thread may not apply.)

I have downloaded AfterBurner, Cody's MS Toolkit, and various other items. But which one -- if any -- is most likely to lead to success, with the least chance of going off of a cliff ? And how should I use it ?

In retrospect, it is looking like having gone with that BIE version was a horrible mistake. If there was some reliable way of transferring everything, in one clean shot (like Laplink PC Mover or certain other apps claimed to be able to do), I would even consider that. Non-BIE Ultimate has been trouble-free.

Your help would be much appreciated.

 

No, I have both -- but on different computers. The case in question involves the BIE Enterprise x86. The Ultimate is x64, not from BIE, and has no issues I'm aware of.
