Unfortunately, there is no solution for the account issues. But you can try these steps.
Possible solution to problems with the PC version of the game:
1. Check what folder the game is installed in. There should not be any special characters in putin to the game folder. For example "C:\Users\пользователь\Desktop\игры". Here "игры" and "пользователь" is an unacceptable character. The path to the game must consist only of english (Latin) letters, for example "C:\Games\".
2. Your system may also lack the .NET frameworks
3. If you have Windows 7, that may be the problem and you should upgrade to a newer version of Windows.
4. Perhaps your antivirus is interfering with your connection to Google servers or your country has blocked access to Google servers.
