If you have a problem/bug in the Steam version of the game - you need to write to the support and specify your Steam ID in numbers.
You can find your Steam ID either in your profile link or in your profile itself:
1. Open your profile in the Steam community.
2. Select "Edit Profile".
3. If you have never set up a personal link to your Steam account, your 64-bit ID will be listed under the "Personal Link" field in the format 76561198#########.
4. If you have customized a personal link to your Steam account, delete the text in the "Personal Link" field to see your 64-bit ID in the link below it.
