IMPORTANT! If you have troubles with client
1. Download new client from: (link - client)
or 2. If you were using "DBLClient.exe" (OpenGL) try to log with on "DBLClientDirectX.exe", and if you were using "DBLClientDirectX.exe" try to log in with "DBLClient.exe" (OpenGL).
If it worked for you, go to the folder with clients and delete "DBLClient.exe" and rename "DBLClient.exe_" to "DBLClient.exe". If it didn't work for you, download a new client from official site (check p. 1.)
