IIRC There were a very small number of accounts that were corrupted during our soft launch period. I think it was something like only the first 1000 wallets were affected, but I could be off... it was a long time ago. Did you happen to work for stripe at the time? I feel like it was only the prelaunch wallets we gave out during our client testing period that got hosed beyond recovery.

But other than that, most people who lost their accounts tend to have bad password management skills, frankly. They certainly could also be victims of bugs in our client... it turns out one of our too ambitious goals during our early days was building a banking-grade wallet experience that offered broad browser support with as few developers as we were. Our support queues however were a sobering lesson in how bad passwords are for security and usability and it was just too much for our community manager and us on the dev team to handle. Our bad... we were trying our hardest believe me.

I apologize if you got hosed because of a bug. I do know that all of my friends and family accounts (6 of the earliest accounts in the system post launch) were able to successfully upgrade to the new wallet and network as late as sunday of last week. They. like you I imagine, got their free lumens and then promptly forgot about the project. They all scrambled to update their wallets when the craziness was going on at the end of last week with lumens and they all upgraded fine.

I'd be happy to help you troubleshoot you wallet to see if we can recover you lumens... email me at scott@stellar.org and we can work through it privately if you like. I can't guarantee much, however... I'm presently starting on a leave of absence for the next month or so and so the time I can dedicate to support is pretty truncated at the moment.
