@UltimateStratos Hey, had the exact same fail cycle a week ago, tried gutting out the installation files but purposly keeping the registry files so it kept my data - No dice.

Eventually i just compleltly sterilized it, registry files too (using Geek Unintaller) Suddenly it's revived zer0 start up fake outs, but as you'd guess with amnesia. That's the trade off, but a decent bandaid is, IF you enabled "Opera Sync" before the crash. It saved up to your settings, bookmarks, history, passwords etc. That was enough to get me back to speed.

If there's a better solution hope it reaches you ⋄
