There is a file in mydocuments which stores the information. Try backing it up, as it is the file that stores the achievements/favour.
That pool is only for multiplayer LAN games. It does not effect online Skirmish, Pantheon or Custom games.
So once you get negative you're pretty much screwed.
The one thing you can do is go and play custom games:
- Play against a single easy computer.
- Set your starting level to 20.
- Set starting gold to fithy rich.
- Starting war ranking to very high
Basicly max out everything. Win over an over Vs the AI till you're out of negative and have your points and items that you purchased back.
WARNING: I've done this once (did not cheat just got the items I had purchased previously back) and then after playing some more BAM!!!!
Back to negative favor, and all my items previoulsy purchases LOST but one. So frankly I don't think it's worth my time to dig myself out of the hole again or to get back the items I should have.
This for me is a huge sore point, if you're going to have persistant items in your game, they need to be accurate! Losses should not occure. While World of Warcraft had connection issues, I don't think I've ever lost an item or gold in my 4 years of playing!
Anyway, I know they've posted they are going to fix it:

It can't come soon enough IMO -- but I also realize that connection issues are by far more important.
