Your old wallet should still be in the location where you previously used it. Find the 'UTC--' file from there and make a copy. This file can then be loaded into your web wallet with the password you used before. Alternatively if you have your private key you can access your funds via the web wallet aswell.
Or you can copy the UTC file from the old location to the location used by the new wallet - $HOME/.akroma/data/keystore/
Thanx to all, looks like the Akroma wallet moved an UTC file to new location but for some reason was not able to work with it. Now I found this file and placed it back to my custom folder. My AKA coins are OK now.
Let's hope that devs will make their best for Akroma wallet to be smarter and better than now.
