You're left with the last solution of trying to sync Armory with a brand new wallet. Your current situations strongly indicates that the outputs listed in your wallet somehow get Armory to hang. I have ran across one of these wallets recently. As far as getting your BTC out of your wallet, you can start Armory in offline mode and extract your private key list to import elsewhere.

The silent majority of our users run Armory without issues. You fall in the few very difficult cases that take Murphy's law to an extreme. Your first step in helping us debug this is to try and isolate the bug as much as possible. Reproducing it at will would be best.

As for the stability of Armory, the current release (0.90) came with an entirely new database system to keep track of the blockchain, obviously there are some very hard to find bugs that only cater to a tiny minority of users. These bugs are scarce and convoluted enough that it makes tracking them very complicated.

Hopefully the next release (coming soon) will have our latest batch of bug fixes incorporated. Best case scenario, it fixes your situation, worst case scenario, we will have narrowed down the possible candidates.

Few users do this, but if you were willing to send us a watching only copy of the wallet you can't get Armory to sync with, it could go a long way identifying the issue. You can email it to support@bitcoinarmory.com, make sure to mention this thread and ask directly for me. If you'd prefer encrypting the email, we can set something up.
