I've had this problem since the patch came out, except I don't get past the server selection screen.
When the servers will be fully operational (when ppl will be able to log in normally) then try to run your game in Win8 compatibility mode and make sure that either your Windows firewall, your anti-virus system or the router (if you have any) doesn't block allods.
It might be also that you have problems with password, maybe you have cheged it not so log ago and now you try to login with the old password.
(very far fetched but) also check in your game folder under:
path_to_your_game\Allods Online EN\data\Packs\main.xml
open the *.xml file in any program and look at the 2nd line. It should be looking like this:
<main build="99" date="1476084058" size="7615100425" torrentbaseurl="http://static.gc.my.com/torrents/" packageprefix="aoen_" buildinfo="7.0.02.49">
the most important thing is the number at the end. If its different and you know you downloaded and installed the patch, then change the number to this one and save the change (while the game is turned off) and then start the game.
ps. If you have 2 graphic cards, then make sure that allods is running on the best one (not the integrated one). It hangs on 18% bcz it's reading maps and location files and since the patch those files need more memory and better equipment then it was before (Allods now takes around 2GB RAM instead 1.5GB as it was before patch).
