Hello,
- What is your antivirus ? Firewall ? Avast antivirus
This antivirus is well known to have some issues with Allods Online.
I would suggest to remove it from your computer, choose a new antivirus, install it, restart your computer and try again.
Always launch the game in administrator mode, and check your firewall settings, on your computer, and your modem.
Check your Internet Explorer settings too. Go to "internet options" and change them to "default".
Try to launch the game with the Allods launcher (in your Allods Online/bin/ folder -> launcher.exe), in administrator mode.
If nothing works, please submit a ticket to customer support :

Tell them the most informations you can about your computer and your internet connection.
Feel free to send a DXDiag with your request :
Export a DXDiag report:
Go to Start > Run and type 'dxdiag' (without quotes please) in the 'Open' field and press OK button
Wait for 'green' progress bar to finish loading and then press the 'Save All Information...'’ button
Name the file with some useful info, like your name and the date, and save it where you can find it, like the Desktop, by pressing the 'Save' button
Press the 'Exit' button to quit this application
Maybe someone will have more ideas while support team is trying to solve your issue.
Good luck.
