I tried to manually migrate my account to Steam. After I click to 'Check Status' it ask me to review/agree to the transfer. When I do that it warns me of possible progress loss and next page is an error screen with no code that reads::
An error occurred during your transfer. Don't worry, your account and characters are safe. Please try again.
If your transfer fails multiple times, visit our official help forums.
