I've just downloaded Mist 0.8.1 under Windows 10 (fully up to date). It was working at first, but is now crashing after the sync.
I followed these steps, maybe something here munged the preferences?
Downloaded and ran Mist 0.8.1. I saw the new announcement but didn't click anything.
At that point, I realized I wanted to back up my wallet before proceeding. So I clicked close (X) and opened v 0.7.6. I went to Backup > Accounts and made a copy of everything.
Closed v0.7.6 and re-opened v0.8.1., and clicked Yes for the DAO fork. Mist was having a lot of trouble syncing: it would say it found 2 peers, then 3 peers, then they would disappear. But after a while it synced. In the meantime, I was able to launch the application and see the new interface.
After a long sync, I don't know if I quit or the application crashed. However now, when I open it and click Launch the Application before it syncs, it crashes, and if I wait to let it sync, it crashes when done syncing. So I can't get to the interface.
I found the log, but I wouldn't know what to look for.
Thanks for any help.
