@dlorde I suspect there is something strange going on with your installation. Please contact Matt so we can take a look. TB 11 does not "corrupts the metadata file used by TB 10 so that TB 10 won't allow log-in" as far as we know so far based on hundreds of installs. If this is happening for you, we'd like to find out why.
Don’t worry. If you login, you will see your brain in the brains list. Click the person icon on the top right and log in to your account.
It looks like you tried to import your brain data as a folder, which is why it is displaying using the IDs (numbers) as thoughts. The Brain that you created via this import process (U01) can be deleted once you have everything working again. Do NOT delete the folder from your hard drive.
If you don’t understand these instructions, call support tomorrow morning and someone will walk you through them.
