Thanks for the linkies; they are similar to the ones I found myself.
Looks like it's a case of EA printing Keys on their manuals that just don't work. Neither the Crysis nor the Warhead key work on stock Crysis Wars (never mind MW:LL). Sent an email to beleaguered EA/Origin support, for all the good that'll do.
(Note, they actually emailed back and told me how to backup my registry ROFL, no help on the issue, just "backup your registry")
Epilogue: Ended up calling EA Support after it was clear emailing wasn't going to get it done. Caught a rep named Gabby who gave me a new CD Key and now I'm in MW:LL
So kudos to EA phone support -- 1-650-628-1001 -- I called at around 7pm CST on a Tuesday and it took about 10-15 minutes to catch her, and about 15 more to resolve it.
So... I walk into MW:LL, after installing all and updating. I appear as the BA. Decide to buy the Osiris-C. Go down the wrong ramp, don't see it. Go back up, go down another ramp which I thought was "1" -- Get the notice that my Mech Has Been Disassembled! Down to 30k cbills. Screwed. <insert rage-face here> Even after reading the basic guide, had no clue this was going to happen...
So I hop out of the server and then pop back in. Miraculously, I get my starting amount of cbills back. So I go down to mechbay 1 and THEN buy my stuff. Get to see the mech being "created". OK, there it is. Now I guess I gotta jump into it. So I use the jump button. There's a highlighted "Enter". I hit my re-mapped "enter" key, which is forwardslash. Nothing. Hit "f". Nothing. I'm doing a bloody tap-dance on my osiris (harder than you'd think), with the Highlighted message "Enter" laughing at me. Literally pounding on the / and F keys. Nothing... until the mech vaporizes (of course, because that's what mechs do, ya know) and apparently I fall to my death, since the screen jumbles, gets fuzzy and I see "suicide" light up on the respawn. Yea, right.
Turns out, that I unwittingly applied "forwardslash" to 'use/get-in/eject' while in Actionmapper, and ASSUMED that it, you know, knew what the "/" key was. Nope, buzz, bad answer, Actionmapper had no clue what my "/" key was -- you could pound it all day and never register. So, always test your keypress out before you assign it... <sigh>
