Database Update Error

[sedvi]

Hello!
I created a new Database and imported all the hands and configurations from my old obsoleted database.
After a new start, I got the following message.



Holdem Manager 2 has added new features that require updating your database. This process may take several hours to complete depending on the size of your database

Would you like to update your database now ?

As I pressed OK and I got the following error message.


Error: Collection was modified; enumeration operation may not execute.

There is nothing in error_log.txt. Only the following message in normal log.txt


12:49:16.895 [Main:1 - Bootstrapper.OnCurrentPlayerChanged] System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

You can close this. (Tough the message and error was strange.)

I created another new database and imported only Hands, without restoring the configurations and the database from the "backup".
